ABSTRACT:
These circuits include a current mirror amplifier (CMA) having an input (master) transistor and at least one output (slave) transistor. The signal translation input circuit comprises a third transistor having a base-emitter junction connected between the input and common terminals of the CMA and a signal voltage input terminal at the collector of the third transistor. The output current of the mirror is a function of the signal voltage applied to this signal voltage input terminal.
