ABSTRACT:
A peak storage amplifier for storing successive peaks of a waveform for a sufficient period of time to insure accurate data transmittal is provided. A differential amplifier is responsive to the waveform and drives a PNP transistor that provides an output. A capacitor stores the peaks of the output waveform as long as a clamp signal is received by a current source that inhibits the current source from sinking the output to ground. Since the PNP transistor is continually reversed biased and the base-collector capacitance is small, the storage capacitor's discharge due to the amplifiers inherent turn-off characteristics is minimized. A compensation capacitor coupled to the differential amplifier prevents the collapse of a Wilson mirror serving as a load to the differential amplifier.
