Low-power CMOS with subvolt supply voltages
نویسنده
چکیده
We first present a circuit taxonomy along the space and time dimensions, which is useful for classifying generic low-power techniques, followed by an analysis of optimal power supply and threshold voltages and transistor sizing for minimizing the energy-delay product of a class of complementary metal–oxide–semiconductor (CMOS) digital circuits.

متن کاملVariable Supply-voltage Scheme For Low-power High-speed CMOS Digital Design - Solid-State Circuits, IEEE Journal of
This paper describes a variable supply-voltage (VS) scheme. From an external supply, the VS scheme automatically generates minimum internal supply voltages by feedback control of a buck converter, a speed detector, and a timing controller so that they meet the demand on its operation frequency. A 32-b RISC core processor is developed in a 0.4m CMOS technology which optimally controls the intern...

متن کاملLogic Design Considerations for 0.5-Volt CMOS
As the operating supply voltage for commercial CMOS devices falls below 2 V, research activities are underway to develop CMOS integrated circuits that can operate at supply voltages well under 1 V. Although dramatic power reductions can be achieved using low supply voltages in high performance applications, the increased subthreshold leakage that results when transistor threshold voltages are l...
