Summary :

An elastic-Vt CMOS circuit is proposed which facilitates both high speed and low power consumption at low supply voltages. This circuit permits fine-grain power control on each multiple circuit block composing a chip, and it is not sensitive to design factors as device-parameter deviations or operating-environment variations. It also does not require any such additional fabrication technology as triple-well structure or multi-threshold voltage. The effectiveness of the circuits design was confirmed in applying it to specially fabricated 16-bit adders and 4-kb SRAMs based on 1. 5-V, 0. 35- µm CMOS technology.
