Abstract
A comparatorthat detects the difference between a high frequency signal detected by a detectorand a feedback signal A output from a comparator; a comparatorthat detects the difference between the difference detected by the comparatorand a feedback signal B output from an adder; and a loop filterthat passes only a prescribed low frequency band of the output signal of the comparatorare provided, in which an amplitude sensitivity adjusteradjusts the amplitude sensitivity of a variable gain amplifierin accordance with the rate of change of the signal passing through the loop filter, thereby controlling the gain of the variable gain amplifier
