Abstract

Charge transfer devices are adapted to provide all possible forms of combinational logic functions by using combinations and variations of a basic state inversion-bit regeneration element. This basic element employs electrically floating means in the vicinity of a charge transfer device to sense the presence or absence of charge therein and to control the transfer of a newly-generated amount of charge away from an independent source.
