Abstract

PURPOSE:To reduce the fluctuation in phase of an output signal attended with the level change in an input signal by forming the titled circuit of a linear amplification circuit, a nonlinear amplification circuit, a voltage controlled phase variable circuit, a circuit detecting the peak value of an output signal of the linear amplifier circuit, and an operational amplifier circuit converting the peak value on a predetermined function to generate a control voltage. CONSTITUTION:The output of the linear amplifier circuit 1 is supplied to the peak value detection circuit 5 on one hand, and the change in the input amplitude is extracted as a change in a DC voltage and the result is fed to an operational amplifier circuit 6. The operational amplifier circuit 6 amplifies the input voltage so as to obtain a control voltage to compensate the phase fluctuation in the curve of a predetermined function, and the result is outputted to the voltage controlled phase variable circuit 4. The control voltage controls the voltage controlled phase variable circuit 4 to reduce the phase fluctuation of the output attended with the change in the input amplitude of the nonlinear amplifier circuit 2.
