ABSTRACT:
An amplifier circuit according to the present invention includes a plurality of input nodes receiving a plurality of input voltages (VI1to VIR), a plurality of differential amplifiers provided corresponding to the plurality of input nodes, each having one input which receives a voltage of the corresponding input node, and a control circuit generating a control voltage (CONTROL) that follows a minimum voltage or a maximum voltage of the plurality of input voltages (VI1to VIR) from outputs of the plurality of differential amplifiers and supplying the generated control voltage (CONTROL) as a common value to the other inputs of the plurality of differential amplifiers.
