Abstract
A logic gate that includes a first differential amplifier and a feedback circuit. The first differential amplifier has a number of first (e.g., non-inverting) inputs and a second (e.g., inverting) input, receives and senses input signals applied to the non-inverting inputs, and provides a differential output that is a particular logic function (e.g., an 'OR') of the input signals. The non-inverting inputs may correspond to the gates of a number of transistors coupled in parallel to form an OR function. The feedback circuit detects the (e.g., non-inverting node of the) differential output and provides a control signal for the inverting input of the first differential amplifier. The logic gate typically further includes a second differential amplifier that senses and further drives the differential output.
