NEW CMOS TRIODE TRANSCONDUCTOR

Abstract

A new CMOS transconductor is proposed, which is built around two conversion transistors operating in the triode region with their source and drain voltages kept constant. The proposed transconductor has an input swing range of 7V peak to peak within 1% THD at supply voltages of +/-5V and a large transconductance tuning range. Moreover, it can operate satisfactorily regardless of the transistor body connection.
