Abstract

Circuits and methods to realize a power-efficient high frequency buffer. The amplitude of a buffered signal is detected and compared with the amplitude of the input signal. The comparison result can be fed back to the digitally-controlled buffer to keep the output gain constant. By using feedback control, the buffer can be kept at the most suitable biasing condition even if the load condition or signal frequency varies.
