Abstract
A multiplexer circuit includes pairs of control elements such as CMOS transistors serially connected between common circuit nodes to conduct current therebetween in response to one of each pair of control elements being selectively biased to conductive or non-conductive states by an applied control signal. The current enabled to flow between circuit nodes through a pair of control elements biased to conductive state is determined by the magnitude of an applied signal, and a current-difference circuit compares the current flowing between circuit nodes with a reference current to produce an output signal representative of the applied signal which is selected in response to an applied control signal.
