An amplifier stage suitable for current conveyors and current mode feedback operational amplifiers has low input resistance and operates at low power. The amplifier stage comprises a buffer having inverting and non-inverting inputs and a pair of current outputs, and a pair of multiple output current mirrors which operate in conjunction with the buffer to generate an output current at a high gain node in response to an input signal applied to the buffer inputs. Each multiple output current mirror has a low impedance current input for receiving current signals generated by the buffer and multiple high impedance current outputs for providing current feedback to the inverting input of the buffer and output current to the high gain node of the amplifier stage. The magnitudes of the feedback and output currents are determined by the resistances of current scaling resistors associated with the low impedance current input and each of the high impedance current outputs.
