ABSTRACT:
An improved CMOS current source circuit capable of constantly generating a certain reference voltage irrespective of an analog supplying voltage, a substrate temperature, and a temperature variation, which includes a start unit for driving the CMOS current source circuit in accordance with a start signal; a bias current generating unit driven by the start unit for generating a bias current in accordance with an analog voltage, a substrate voltage, and a temperature variation; a current input unit for inputting a bias current; and a current compensation unit for receiving a bias current through the current input unit and for compensating the bias current in accordance with an analog voltage, a substrate voltage, and a temperature variation and for generating a reference current.
