Constant current source-Count

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.Input current value, power dissipation, power supply voltage and other parameters can be used to obtain the output result.
