Abstract :
In this paper, a CMOS implementation of a Gm-C low voltage micropower biquad is presented. The filter is based on a novel floating gate MOS (FGMOS) Gm-C lossless integrator. Operating at 0.8 V with a bias current of 50 nA, the integrator has a power consumption of 120 nW achieving a dynamic range (DR) of 74 dB. The filter parameters can be adjusted by more than a decade having an upper cutoff frequency of 28 kHz for a 15.7 pF integrating capacitance.
