A system for a constant current source circuit utilizing CMOS technology. The system includes a constant current source circuit that includes a bias circuit that outputs a bias signal and a switch circuit that has a switch input coupled to receive the bias signal, a switch output, and a switch control that is coupled to receive an input signal. The current source circuit also includes an output circuit that has a first input coupled to the switch output and a second input coupled to the input signal. The output circuit provides an output signal that has constant current.
