STABLE RADIO FREQUENCY (RF) AMPLITUDE DETECTOR

Abstract: various examples in accordance with the present disclosure provide a stable rf amplitude detector. some embodiments include a diode bridge circuit comprising a plurality of diodes, wherein at least a portion of the plurality of diodes are biased together and configured to rectify a positive peak of an rf input and a negative peak of the rf input. some embodiments include a differential amplifier circuit comprising a plurality of differential amplifiers. the differential amplifier circuit may be configured to: (a) compare the positive peak of the rf input rectified by the diode bridge circuit to a positive dc setpoint input, (b) compare the negative peak of the rf input rectified by the diode bridge circuit to a negative dc setpoint input, and (c) output an error value.
