ABSTRACT:
A voltage/current conversion circuit giving an output current which is proportional to an input voltage. The circuit includes an operational amplifier to one input of which the input voltage is applied, first and second transistors, to the commonly connected bases of which the output of the operational amplifier is applied, and a feed-back path connecting the collector of the first transistor to the other input of the operational amplifier. With the circuit thus constructed, the output derived from the collector of the second transistor is in proportion to the input voltage.
