ABSTRACT:
An impedance conversion circuit is comprised of an NPN transistor of which the gate is supplied with an input voltage, a first current mirror circuit for supplying a current corresponding to the input voltage to the collector-emitter path of the NPN transistor, a second current mirror circuit which is controlled by a current supplied from the first current mirror circuit to feed back a current corresponding to the current to the gate of the transistor, a load connected between the emitter terminal of the NPN transistor and ground, and an output voltage being derived from the emitter of the NPN transistor.
