Crosstalk cancellation in a receiver

Abstract:

Embodiments relate to systems, methods, and computer-readable media to enable design and creation of crosstalk cancellation circuitry for a receiver (e.g. an AC coupled DDR5 receiver). One embodiment is a receiver apparatus with crosstalk victim and aggressors lines. The cancellation circuitry involves an amplifier and buffering circuitry to provide inductive and capacitive crosstalk cancellation voltages. Some embodiments can additionally involve circuitry for autozeroing modes for AC coupled receiver lines.
