The constant current source is composed of a signal source and a voltage controlled current source (VCCS), and is a current source in which the output current is kept constant.
The basic constant current source circuit is mainly composed of an input stage and an output stage. The input stage provides a reference current, and the output stage outputs a constant current required.
