Abstract :
A new BiCMOS low-voltage transconductor suitable for VHF continuous-time filters is proposed. The transconductance is tunable with a control voltage. The output resistance of the 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
