Abstract
A 4th-order Butterworth lowpass continuous-time filter, based on transconductance-C integrators, for applications in the videofrequency range is presented. Fabricated in a standard 0.8µm CMOS technology (MOSIS HPCMOS26G), the circuit occupies an area of 0.59mm2, including the automatic tuning circuitry, and dissipates 40- mW from a single 5V supply. A simple transconductor is utilized, which provides good linearity and high-speed properties. Experimental results of a 10-MHz, 60-dB dynamic-range, lowpass filter are given.
