A Low-Power High Linearity Gm-C Filter

Abstract:

Article Preview

A low-power, high linearity Gm-C filter is presented and designed.The input transistors of Gm is biased in linear region, and drain-source voltage is constant through feedback loop. The filter is designed in SMIC 0.18μm Mixed Signal CMOS PDK (Process Design Kit) with cutoff frequency 15.74 MHz, Passband ripple less than 0.2dB,while dissipating 2.5mW. It can be used as Baseband filter in RF system.
