Abstract:
A differential receiver with reduced common mode induced propagation delay variance. One implementation of a differential receiver includes a first differential amplifier, a second differential amplifier, and a first current source. The first differential amplifier includes a first transistor pair. The second differential amplifier includes a second transistor pair. The first current source is coupled to a drain node of a first transistor of the first transistor pair. The first current source is configured to generate a variable first current at the drain node as of function of a sum of a variable tail current of the first differential amplifier and a variable tail current of the second differential amplifier.
