Abstract:
An amplifier for continuous high gain, narrowband signal amplification, the amplifier comprising:(a) a first summer, the first summer responding to an input signal and a feedback signal and the first summer producing an active circuit input signal;(b) an active circuit, the active circuit responding to the active circuit input signal and a gain control signal and the active circuit producing an output signal;(c) a feedback circuit, the feedback circuit responding to the output signal and a phase control signal and the feedback circuit producing a feedback signal;(d) a first controller for adjusting the gain of the active circuit, the first controller responding to the output signal and the first controller producing the gain control signal; and(e) a second controller for adjusting the phase of the feedback circuit, the second controller responding to the output signal and the second controller producing the phase control signal.
