ABSTRACT:
A current conversion circuit employing negative feedback includes an operational amplifier, a diode and a time constant circuit cascade connected, a transistor having a base connected to the output of the time constant circuit, and an impedance element connected between the inverting input terminal of the operational amplifier and the emitter of the transistor to obtain conversion current from the collector of the transistor. With this arrangement, the inventive circuit can perform the same functions as a conventional current conversion circuit but has a simpler construction and smaller number of components.
