ABSTRACT:
An amplifier operating from a plurality of power sources in which current flows through ground loops between power sources supplying operating power to different stages are eliminated. The output of a voltage amplifying stage is applied to a high input impedance buffer input circuit of a following buffer amplifying stage. The output of the power amplifying stage is voltage divided and applied to a feedback buffer circuit, the output of which is applied to an inverting input terminal of the voltage amplifying stage. Accordingly, due to the high impedance of the input of the power amplifying stage and of the feedback buffer, substantially no currents flow between the stages, hence eliminating ground current flows.
