Abstract :
This paper describes a CMOS transconductance cell for the implementation of very high frequency current-mode gm-C filters. It features simple pseudo-differential circuitry employing small device size transistors and yielding a power dissipation of less than 1 mW/pole at nominal 3.0 V supply voltage. Self-biased common-mode voltage designed to minimize mismatch errors, improves noise and stability behavior. Short channel effects are analyzed and simulation results are presented
