ABSTRACT:
In a current amplifier, a current obtained by holding an input current from an input terminal by a first current sample/hold circuit is added through a connection to a current obtained by inverting the input current by a current inverter to generate a current twice the input current. This current is alternately sampled and held by second and third current sample/hold circuits and alternately output to an output terminal.
