Abstract:
1. An analog feedback amplifier comprising: a first comparator unit that takes the difference between an input signal and a first feedback signal; a second comparator unit that takes the difference between an output signal of the first comparator unit and a second feedback signal; a power amplifier unit that amplifies an output signal of the second comparator unit; a first amplitude regulator unit that regulates amplitude of an output signal of the power amplifier unit; a second amplitude regulator unit that regulates amplitude of the output signal of the second comparator unit and supplies a signal passing through the amplitude regulation to the second comparator unit as the second feedback signal; a delay unit that delays the output signal of the second amplitude regulator unit; and a third comparator unit that takes the difference between an output signal of the first amplitude regulator unit and an output signal of the delay unit, and supplies the differential signal to the first comparator unit as the first feedback signal.
