The operational-amplifier (op-amp) inverting amplifier is versatile on account of its ready adaptability for such functions as current-to-voltage conversion, integration and differentiation. The op-amp noninverting configuration is not readily amenable to these operations, and in order to obtain a noninverting output one frequently cascades an op-amp inverter to the respective functional circuit. This approach suffers from requiring two additional stable resistors for realizing the inverter. An attractive alternative is proposed which uses a matched-transistor current mirror, and requires just as many passive elements as the inverting configuration.
