Abstract
In an amplifier comprising a signal-amplifying circuit for amplifying an input signal to the amplifier and a power-supply circuit for supplying power to the signal amplifying circuit for operation, there is provided an additional amplifying circuit driven by the output signal of the signal-amplifying circuit and powered from said power circuit. Changes in the power-supply currents for the respective amplifying circuits cancel each other. Thus, the total current supplied from the power supply circuit is maintained constant.
