Abstract
A signal translating circuit comprises first and second transistors connected to each other in such a manner that a collector of the first transistor is coupled with a base of the second transistor and an emitter of the second transistor is coupled with a base of the first transistor so as to form a negative feedback circuit arrangement, an input resistor connected between the base of the first transistor and a source of an input voltage signal for converting the input voltage signal into an input current signal to be supplied to the base of the first transistor, a biasing current source connected to the base of the first transistor, first and second current sources supplying the same currents and connected to the emitter of the first transistor and a collector of the second transistor, respectively, and means for deriving an output current signal from the collector of the second transistor.
