Abstract

This paper describes a realization of a linearized transconductor using a CMOS complementary pair. The proposed transconductor is driven by a grounded signal source. How to cancel the offset current is described, Moreover , how to control the transconductance is described . It is shown that power consumption of the proposed transconductor without the control circuit is about half as low as that of the conventional Wang’s OTA through computer simulation.
