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.

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 ...

While metastability—an indeterminate state in a digital circuit—is far from a new topic, increasingly faster signal rates can put your design at greater disk to the phenomena. Certainly you should ...

Technology developed for driving synchronous FETs in flyback topologies can be directly applied in LLC topologies. This technology offers significant gains in efficiency for applications with low ...

Power supplies that use diodes to rectify an ac voltage to obtain a dc voltage must deal with inherent inefficiencies. A standard diode or ultra-fast diode can have a 1-V forward voltage or higher at ...

Given the growing importance and impact of portable, battery-operated devices in today’s society, it’s easy to understand why power consumption has become such a critical factor in IC design. But it’s ...

An asynchronous DSP offers better power, performance, and reliability than one based on standard synchronous logic. It also enables simpler and less expensive PCB and power supplies. Until today, the ...

Hardly anything inside a computer would seem to be more basic, or more necessary, than the processor “clock”—the little crystal oscillator whose rhythmic ticks ultimately regulate everything the ...
