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

Analog feedback amplifier

An analog feedback amplifier is capable of suppressing extraneous phase fluctuations and broadening a bandwidth by preventing effects of a group delay element by using an amplitude regulatorand a delay line
