Abstract

A low voltage, low power bulk-driven transconductor for low frequency Transconductance-C (\(G_m-C\)) filters is proposed. The transconductor is designed in UMC 180 nm technology with supply voltage of 0.5 V. The transconductance (\(G_m\)) is tunable from 12 nS to 100 nS, which is suitable for low frequency \(G_m-C\) filters. The power consumption is 120 nW. As an application, a \(2^{nd}\) order Butterworth low pass filter (LPF) with cutoff frequency tunable from 110 Hz to 960 Hz is designed.
