Abstract

A second order fully integrated low pass filter with cut-off frequency variable in the range 1.5-15 Hz is presented. The filter is based on a recently proposed CMOS transconductor topology combining G _m values of the order of a few nS with large input ranges and suitability to single-ended filter architectures. The performances are validated by simulations performed on a prototype designed with the 0.35 mum BCD6 process of STMicroelectronics. In particular, a dynamic range of 70 dB and power dissipation of 60 muW have been obtained with a corner frequency of 1.5 Hz
