Abstract:
An apparatus for dynamically adjusting the bias of an amplifier, comprising:(a) an inverse Fourier transform processor receiving a plurality of inputs; (b) a multiplexer, the input connected to the output of the inverse Fourier transform processor; (c) a plurality of buffers connected to the output of the multiplexer; (d) a demultiplexer receiving inputs from the plurality of output buffers, the output of the demultiplexer connected by a circuit to the input of the amplifier; (e) a peak detector and hold circuit, the input of the circuit connected to the output of the inverse Fourier transform processor; (f) a selection means, the selection means receiving an input from the peak detector and hold circuit, and responsive to the input selecting a bias point for the amplifier, the selection means output connected to a bias control circuit, the bias control circuit controlling the amplifier's bias point.
