A second order, single ended, fully integrated low pans filter with cut-off frequency tunable in the range 1.5-15 Hz is presented. The filter is based on a recently proposed CMOS transconductor topology, combining Gm values of the order of a few nS with large input ranges and suitability to single-ended filter architectures. The circuit has been designed and fabricated using 3.3 V-0.35 mum CMOS devices from the STMicroelectronics bipolar-CMOS-DMOS process BCD6. The tested prototype occupies a 960 times 350 mum2 area and requires a supply current ranging from 50 to 500 muA, depending on tuning. A dynamic range in excess of 60 dB has been estimated from experimental measurement

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 H
