Abstract

Various circuit techniques for implementing ultra high speed circuits use current-controlled CMOS (C3MOS) logic with inductive broadbanding fabricated in conventional CMOS process technology. Optimum balance between power consumption and speed for each circuit application is achieved by combining high speed C3MOS logic with inductive broadbanding /C3MOS logic with low power conventional CMOS logic. The combined C3MOS logic with inductive broadbanding /C3MOS /CMOS logic allows greater integration of circuits such as high speed transceivers used in fiber optic communication systems.
