摘要：

A compact transconductor based on transistors operating in the triode region is presented. A novel V-I conversion stage made up of current dividers is proposed. The circuit allows tunability by adjusting a dc current and the transconductance is independent of transconductance parameter of the triode transistors. Besides, the circuit is simple because feedback structures to fix source-drain voltages of triode transistors are not needed, saving area and featuring low power consumption. Measurement and simulation results are presented and analyzed for validating the proposed technique.
