Low voltage microprocessors, the inevitable future

摘要

The laws of physics will necessitate that future microprocessorsnoperate with ever decreasing power supply voltages. Smaller processntechnologies, higher integration, and faster internal frequencies arenrequiring the reduction of the power supply voltage. This paper is anninsightful look at the challenges of designing with low voltagenmicroprocessors. An embedded reference design based on a militarynPentium processor is presented as a primary example. Topics included innthe paper include explanation of the reasons for lowering supplynvoltage, techniques for interfacing devices of different voltagentechnologies, and the creation of an accurate low voltage power supply
