Abstract
A voltage-to-current converter in which the base-emitter voltage of an output transistor (T1) is compensated by means of the base-emitter junction of a transistor (T2) so that the voltage across an impedance (Z1a) in series with the output transistor is equal to the input voltage (Vi). The current through the impedance (Z1a) is then equal to the output current Io, each of which is then linearly proportional to the input voltage (Vi).
