A CMOS transconductor that operates with increased dynamic range while maintaining one or more other basic operating characteristics at substantially the same value in comparison to a prior art transconductor circuit is provided. One embodiment, among others, comprises an input stage circuit comprising several pluralities of transistors with each plurality configured such that certain terminals of the transistors are electrically connected, and the several pluralities are electrically interconnected through one or more terminals of each plurality. Another embodiment comprises modifying an input stage of an existing transconductor circuit to provide a transconductor circuit that operates with increased dynamic range while maintaining one or more other basic operating characteristics at substantially the same value in comparison to the existing transconductor circuit.
