ABSTRACT:
A current source circuit according to the present invention is provided with an output terminal 100, a bias voltage source 21, N channel MOS transistors 2 and 1 and P channel MOS transistor 3. The source of transistor 2, the drain of transistor 1 and the drain of transistor 3 are connected to a common node, the drain of transistor 2 is connected to output terminal 100 and the gate of transistor 2 is connected to bias voltage source 21. Conductions of transistors 1 and 3 are dynamically controlled in response to an external signal. As a result, it is possible to implement a current source circuit having a small number of devices and enabling an operation at a high speed.
