Book excerpt: Corporate Explorers Transform Disruption Into Opportunity With This Proven Framework Innovation used to be seen as a game best left to entrepreneurs, but now a new breed of corporate managers is flipping this logic on its head. These Corporate Explorers have the insight, resilience, and discipline to overcome the obstacles and build new ventures from inside even the largest organizations. Corporate Explorers are part entrepreneurs, using innovation disciplines to jump start cutting-edge ideas, and part change leaders, capable of creating support for investment. They see that corporations already own the ideas, resources, and—critically—the talent to build new ventures. Companies like Amazon, Microsoft, Bosch, LexisNexis, and Analog Devices enable managers to put these assets to use and gain an upper hand over startups that threaten to disrupt them. Corporate Explorer is a guidebook to the practices that enable these managers to go from idea into action. It demonstrates how success is not only possible but may offer entrenched companies better odds than venture-capital backed startups. This actionable and proven framework explains how managers can become successful corporate innovators; it includes tools to: Learn how to apply innovation practices with greater discipline Turn great ideas into a full-time job as an innovation leader Experiment with and scale original business models Transform innovation programs into a thriving source of new business Attract, retain, and motivate entrepreneurial talent Energize employees by creating a realistic way to innovate These lessons come from the trailblazers of corporate innovation—Andrew Binns (Change Logic), Charles O'Reilly (Stanford Graduate School of Business), and Michael Tushman (Harvard Business School)—who have decades of experience helping entrepreneurial-minded executives activate employees to become Corporate Explorers. Entrepreneurs take notice—it's time for Corporate Explorers to set the pace and chart the course for disruption.

Book excerpt: The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits.
