Abstract

This paper presents a new configuration of linear CMOS subthreshold operational transconductance amplifier (LSOTA) working at 1.5 V with very low power consumption. Based on FGMOS technique, the developed OTA has a wide input range and small Gm, suitable for implementing low frequency analog and monolithic continuous-time filters. For demonstration a low pass second order filter was designed and simulated. The power consumption of the filter is less than 2 μW and the topology achieves 76 dB linearity for fully balanced input dynamic range up to 1 Vpp at 1.5 V supply voltage.
