Michael R McCoy: Acquisition and storage of analog signals. Electronic Arrays, Smyth Pavitt Siegemund Jones & Martella, January 1, 1980: US04181980 (89 worldwide citation)

An MOS device with a floating gate and a conductively connected gate is operated in that pulses are applied to the latter gate to capacitively charge the floating gate, and the drain potential is compared in-between pulses with the analog signal. Pulse application is stopped when agreement has been ...
