Abstract

The design of widely programmable low-pass second order G(m)-C filter for telecom applications is presented. A digital tuning scheme is proposed for getting a frequency programmability range from 1MHz to 40MHz compensating the technological spread. The digital tuning circuitry can be turned off, during signal processing. A 0.18mum CMOS technology with a 1.8V power supply has been used for the filter design. A 62dB constant dynamic range is obtained for the filter programmability range by switching input transistors sizes and bias currents of each OTA of the filter.
