Abstract
CMOS circuitry used to multiplex between data inputs suffers from high sensitivity to power supply noise, resulting in delay variations. By utilizing current controlled inverters in a multiplexer structure, power supply insensitivity can be achieved with either of two multiplexing methods. The first method places switches on the data inputs while the second places the switches on the analog bias voltages inherent to a current controlled inverter.
