Abstract

A sort of dynamic biasing circuit, used in biasing receiving of a collective current of variable power input signal amplifiers, including: the device for obtaining input signals representative specimen signals; a signal base detecting circuit, forming oscillation peak for detection of continuous specimen signals, with output of a pair of DC signal; and biasing regulator, connection to the control end of the amplifier.
