Abstract :
A new transconductor is proposed which uses a bias feedback technique and has a simple configuration and a good high-frequency performance. The proposed transconductor is tunable by adjusting the bias current, and suitable for application to highly linear continuous-time filters. Experimental results show that the total harmonic distortion (THD) of the output current is less than 1% for the differential/single-ended input signals of up to 6.0 V/4.3 V (peak-to-peak) when the supply voltages are +or-5 V.
