Abstract :
A new low-voltage BiCMOS transconductor which has transconductance tunable by means of a control voltage and is suitable for VHF continuous-time filters is proposed. The output resistance of transconductor is compensated and the resulting output resistance can be fine-tuned by means of a separate voltage. The transconductor has a large bandwidth, due to having parasitic poles at extremely high frequencies. The performance of the transconductor is demonstrated by simulation results
