Abstract :
CMOS current-mode-filters based on a simple integrator operating in the ohmic region are presented. The highlights of this approach are their reduced power consumption and silicon area, high speed, programmability and low voltage supply. As an example, a 10.7 MHz biquadratic filter with a tunable Q={0.6~178} is presented
