Low voltage logic operation using higher voltage supply levels

Abstract

A circuit comprises 2<n> modules that are connected in series between a first and a second reference potentials. 2<n>-1 nodes that are arranged between adjacent ones of said 2<n> modules. 2<n> -1 2:1 DC / DC converters are arranged, wherein each of said 2<n> -1 2:1 DC / DC converters communicates with a respective one of said 2<n>-1 nodes.

Description

technical field [0001] The present invention relates to the operation of low voltage complex logic macros and / or modules using higher voltage supply levels and lower current levels. Background technique [0002] Over the past decade, complementary metal-oxide-semiconductor (CMOS) processes have produced smaller devices by integrating higher numbers of transistors. For example, current microprocessors are more than a thousand times more powerful than those made ten years ago. [0003] The power consumption of microprocessors is also increasing. Some microprocessors now consume more than 100W. Modern processors built using low voltage CMOS processes employ supply voltage levels that rarely exceed 1v. As a result, CMOS-based microprocessors require current levels in excess of 100A. [0004] Physical barriers begin to limit the amount of current that can flow through these devices. One obstacle involves the voltage drop associated with the distribution of power among these ...
