ABSTRACT:
A voltage-tuned transconductor with reduced even-order and odd-order nonlinearities is obtained by using a pair of control MOS transistors each interconnected between a separate pair of matched balancing transistors. Such transconductors are useful in a variety of applications either with a balanced or single-ended load.
