Abstract
A low voltage, low power bulk-driven transconductor for low frequency Transconductance-C (G<inf>m</inf> - C) filters filters is proposed. The transconductor is designed in UMC 180nm technology with supply voltage of 0.5V. The transconductance (G<inf>m</inf>) is tunable from 12nS to 100nS, which is suitable for low frequency G<inf>m</inf> - C filters. The power consumption is 120 nW. As an application, a 2nd order Butterworth low pass filter (LPF) with cutoff frequency tunable from 110Hz to 960Hz is designed. © Springer Nature Singapore Pte Ltd 2017.
