In this paper a new voltage buffer to realize high speed and low power dissipation switched-capacitor filters is proposed. The drain-follower achieves 300MHz bandwidth with 2pF load; DC gain of 0.993V/V, 1mV offset voltage, -60 dB total harmonic distortion at 0.4 VPP output voltage and 58.5μW power dissipation from 1.5V supply. A unity-gain buffer switched-capacitor biquad filter has been implemented in 0.5μm CMOS technology. The circuit has been sending for fabrication. Simulation results of the biquad filter indicate operation at 100 MHz with 6mW power consumption from a 1.5 V supply can be achieved.
