A circuit technique for improving high frequency performance of current-controlled transconductor elements in transconductance-capacitance (gm-C) based monolithic filters. The circuit detects the output impedance of the transconductance transistors inside the transconductor element, regenerates and applies a negative conductance to the output of the transconductor. By cancelling the transistor output impedance, the total differential mode output impedance of the transconductor element can be maximized.
