Abstract
Push-pull flux quantum gate array cells synchronously process a pair of polarized data signals. These polarized data signals can be derived from dual polarity data signals by separating the input signals into positive polarity data signals and negative polarity data signals. At least one logic or arithmetic operation is performed on each of the positive and negative polarity signals to produce modified positive and negative polarity signals respectively. These modified positive polarity and negative polarity signals can also be combined to produce a modified dual polarity output data signal. Numerous logic operations can be achieved in gate array cells which perform this signal processing method. By using push-pull flux quantum circuits, the need for auxiliary timing signals or interferometers is minimized.
