ABSTRACT:
A transistor is connected to form a diode and connected with another transistor so that the base and the emitter is connected to the base and the emitter of the other transistor, respectively, thereby to constitute a partial current mirror. A plurality of the partial current mirrors thus constituted are serially connected between an input terminal and a reference terminal, and an output terminal is connected to the collector of a partial current mirror which is directly connected to the reference terminal. Transistors of the same polarity are used to obtain an output current larger than an input current. On the contrary, to obtain an output current smaller than an input current, the transistors constituting the partial current mirror directly connected to the reference terminal are made to have the opposite polarity to the transistors constituting other partial current mirrors.
