Abstract :
A new low-voltage BiCMOS triode transconductor with improved linearity suitable for VHF transconductance filter is proposed. Improved linearity is achieved using a translinear crosscoupled circuit. The output resistance of the transconductor is compensated. 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
