Abstract
A differential input receiver with hysteresis on both sides of the reference voltage may include a two-input, one-output differential amplifier including two input transistors having a common terminal connected together. The control terminal of each transistor may be connected to one of the inputs of the differential amplifier. The output of the differential amplifier may be connected to a set of cascaded digital inverters/buffers, and an output of each digital buffer may be connected to the control terminal of a feedback transistor. The feedback transistor may be connected in parallel across each of the input transistors so that when one input voltage increases above or decreases below the input voltage at the second input by a predetermined threshold value, the feedback transistors operate to provide positive feedback to facilitate a rapid switching action at the output.
