Abstract
Disclosed is a half-power buffer/amplifier. The half-power buffer/amplifier includes first and second amplifying blocks respectively corresponding to first and second channels, a first output buffer unit controlled by an output from the first amplifying block, and a second output buffer unit controlled by an output from the second amplifying block. Each of the first and second amplifying blocks includes an input unit configured to amplify a first input signal, thereby outputting first and second currents, and an amplifying unit including a first current mirror, a second current mirror, and a bias unit connected between the first current mirror and the second mirror. Nodes in the first and second amplifying blocks are selectively connected to source/drain terminals of transistors in the first and second amplifying blocks in response to a control signal.
