Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Continuous scaling down of CMOS device sizes and an accompanied increase in device switching speeds prompts the design of mixed-signal systems with increasingly complex digital signal processing and control algorithms accompanied by simpler analog circuitry. Analog to digital converter (ADC) is an essential mixed-signal component of modern receivers, where signals sensed from the source are converted to digital for further signal processing on them. In this dissertation, calibration techniques are presented which allow ADCs to be designed with large inherent gain and offset errors. The concept of arbitrary radix multistep conversion is presented, along with algorithms that enable reduced radix conversion with digital correction in pipelined or algorithmic ADCs. Calibration techniques that account for linear and nonlinear gain error are presented and adapted to the popular 1.5 bit/stage pipeline architecture. Calibration is performed purely with digital post-processing on ADC output bits, with no changes occurring in the analog hardware. In this dissertation a WCDMA/WLAN receiver architecture is presented and specifications are derived for all its components. Concept of reconfigurable ADC design is presented, which allows speed and power consumption optimization. Reduced radix digital correction, linear and nonlinear calibration and background-calibrating queues are presented and combined in two behavioral models. The reconfigurable ADC was fabricated in AMI0.5u 3V CMOS process, and achieved 55dB dynamic range at 45MS/s, consuming 51mW power. The reconfigured calibrated ADC was simulated in TSMC 0.18u 1.8V CMOS process, and achieved 63dB dynamic range at 25MS/s, consuming 3.6mW power. Measurements of the capture card showed a 1.6bit improvement in resolution with the use of calibration algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: "Analog-to-Digital Converter (ADC) microcircuits are required to meet stringent accuracy specifications in spite of their analog components' inherent nonidealities as well as the accuracy limitations due to fabrication technology. In this thesis, a 3-step Nyquist rate ADC is presented which makes use of bitstream processing to calibrate the digital-to-analog converter (DAC) and the residue amplifier, while using the same hardware to calibrate the sub-ADC. The system is designed to provide programmability and calibrate undesired circuit characteristics such as offset, gain error, and nonlinearity. Thus, the DAC can tolerate gain errors much higher than the standard amount, and has the potential to completely cancel nonlinearity and offsets in its transfer function. The offset of the residue amplifier can also be calibrated with this system. Moreover, the system eliminates the need for a reference ladder in the sub-ADC, and calibrates comparator offsets. Simulation and experimental results of the circuits fabricated in a 0.18mum CMOS process are presented." --

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: With the advance of technology and rapid growth of digital systems, low power high speed analog-to- digital converters with great accuracy are in demand. To achieve high effective number of bits Analog-to-Digital Converter (ADC) calibration as a time consuming process is a potential bottleneck for designs. This dissertation presentsa fully digital background calibration algorithm for a 7- bit redundant flash ADC using split structure and look-up table based correction. Redundant comparators are used in the flash ADC design of this work in order to tolerate large offset voltages while minimizing signal input capacitance. The split ADC structure helps by eliminating the unknown input signal from the calibration path. The flash ADC has been designed in 180nm IBM CMOS technology and fabricated through MOSIS. This work was supported by Analog Devices, Wilmington, MA. While much research on ADC design has concentrated on increasing resolution and sample rate, there are many applications (e.g. biomedical devices and sensor networks) that do not require high performance but do require low power energy efficient ADCs. This dissertation also explores on design of a low quiescent current 100k Sps Successive Approximation (SAR) ADC that has been used as an error detection ADC for an automotive application in 350nm CD (CMOS-DMOS) technology. This work was supported by ON Semiconductor Corp, East Greenwich, RI.

This book was released on 2010-10-29 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the fast advancement of CMOS fabrication technology, more and more signal-processing functions are implemented in the digital domain for a lower cost, lower power consumption, higher yield, and higher re-configurability. This has recently generated a great demand for low-power, low-voltage A/D converters that can be realized in a mainstream deep-submicron CMOS technology. However, the discrepancies between lithography wavelengths and circuit feature sizes are increasing. Lower power supply voltages significantly reduce noise margins and increase variations in process, device and design parameters. Consequently, it is steadily more difficult to control the fabrication process precisely enough to maintain uniformity. The inherent randomness of materials used in fabrication at nanoscopic scales means that performance will be increasingly variable, not only from die-to-die but also within each individual die. Parametric variability will be compounded by degradation in nanoscale integrated circuits resulting in instability of parameters over time, eventually leading to the development of faults. Process variation cannot be solved by improving manufacturing tolerances; variability must be reduced by new device technology or managed by design in order for scaling to continue. Similarly, within-die performance variation also imposes new challenges for test methods. In an attempt to address these issues, Low-Power High-Resolution Analog-to-Digital Converters specifically focus on: i) improving the power efficiency for the high-speed, and low spurious spectral A/D conversion performance by exploring the potential of low-voltage analog design and calibration techniques, respectively, and ii) development of circuit techniques and algorithms to enhance testing and debugging potential to detect errors dynamically, to isolate and confine faults, and to recover errors continuously. The feasibility of the described methods has been verified by measurements from the silicon prototypes fabricated in standard 180nm, 90nm and 65nm CMOS technology.

Available in PDF, EPUB and Kindle. Book excerpt: The miniaturization and digitization of modern microelectronic systems have made Analog-to-Digital converters (ADC) key building components in many applications. Internet and entertainment technologies demand higher and higher performance from the hardware components in many communication and multimedia systems, but at the same time increased mobility demands less and less power consumption. Many applications, such as instrumentation, video, radar and communications, require very high accuracy and speed and with resolutions up to 16 bits and sampling rates in the 100s of MHz, pipelined ADCs are very suitable for such purposes. Resolutions above 10 bits often require very high power consumption and silicon area if no error correction technique is employed. Calibration relaxes the accuracy requirement of the individual building blocks of the ADC and enables power and area savings. Digital calibration is preferred over analog calibration due to higher robustness and accuracy. Furthermore, the microprocessors that process the digital information from the ADCs have constantly reduced cost and power consumption and improved performance due to technology scaling and innovative microprocessor architectures. The work in this dissertation presents a novel digital background calibration technique for high-speed, high-resolution pipelined ADCs. The technique is implemented in a 14 bit, 100 MS/s pipelined ADC fabricated in Taiwan Semiconductor Manufacturing Company (TSMC) 0.13 [mu]m Complementary Metal Oxide Semiconductor (CMOS) digital technology. The prototype ADC achieves better than 11.5 bits linearity at 100 MS/s and achieves a best-in-class figure of merit of 360 fJ/conversion-step. The core ADC has a power consumption of 105 mW and occupies an active area of 1.25 mm2. The work in this dissertation also presents a low-power, 8-bit algorithmic ADC. This ADC reduces power consumption at system level by minimizing voltage reference generation and ADC input capacitance. This ADC is implemented in International Business Machines Corporation (IBM) 90nm digital CMOS technology and achieves around 7.5 bits linearity at 0.25 MS/s with a power consumption of 300 [mu]W and an active area of 0.27 mm2.
