Flexfet Independently-Double-Gated CMOS for Dynamic Circuit Control

Abstract

Dynamic control of threshold voltage (Vt) using Flexfet™ independently-double-gated CMOS provides circuit tuning capability to counter global and local process variations. This tuning capability is demonstrated on digital logic gates manufactured with 0.18μm Flexfet CMOS transistors. The dynamic Vt control can also provide a basis for superior efficiency in ultra-low-power applications by allowing dynamic tuning of power versus performance on an as-needed basis.
