Managing the power consumption of ICs is an increasingly difficult challenge, because each new generation of portable device includes expanded features and demands longer battery lives.

Buck regulators are usually the first choice when you design nonisolated step-down regulators unless the ratio of V IN to V OUT is greater than 10, the input voltage is high, or both. Low duty cycle ...

As system-on-chip (SoC) designs grow larger, designers must grapple with serious global timing problems, the effect of wire loading and timing delays and the performance hit associated with supporting ...

Wire delay is beginning to dominate gate delay in current CMOS technologies. According to Moore’s Law by 2016 CMOS feature size should be on the order of 22 nm with clock frequencies reaching around ...

This file type includes high-resolution graphics and schematics when applicable. When converting a higher voltage to a lower voltage, a buck (switching) converter provides much greater efficiency than ...

Clock gating is an effective method of reducing the dynamic power consumption in synchronous circuits. One of the ways to achieve this is by masking the clock that goes to the idle portion of the ...

As the quest grows to manage power in everything from the handheld smart phone to sensors for automotive applications and contactless payment cards, designers are getting hungry for new design ...

There are a number of interesting technologies to keep an eye on in term of how and when they could be adopted for use in SoC design today, some of which include gallium arsenide, GPGPUs, 3D ICs and ...

A voltage-to-frequency converter (VFC) can easily measure current flow and convert it to a digital signal understood by the timer/counter input of a microcomputer (µC) or microprocessor. It's a ...

Moore’s Law has been the driving force behind computer evolution for more than five decades, fueling the relentless innovation that led to more transistors being added to increasingly smaller ...

This unit develops topics in digital system design at an intermediate level. A further study of combinational and sequential logic focuses on issues and design methods which are relevant to modern ...
