Abstract
An analog electrical signal is converted into a binary digital signal by means of an arrangement of semiconductor surface potential wells. During operation, this arrangement converts the analog electrical signal into an analog signal charge packet in one of these potential wells and sequentially subtracts from this analog packet a sequence of reference charge packets representing the binary digital bits of the analog signal, provided that the then remaining signal charge packet is greater than the reference charge packet.
