A circuit can compensate for intra pair skew or mode conversion in a channel by applying a second or corrective mode conversion effect that counters the channel's mode conversion. The circuit can process the common mode signal with a frequency dependent filter prior to injection back into the differential mode. The circuit can implement the reverse mode conversion with passive circuits using integrated resistors and metal oxide semiconductor (MOS) switches. In certain embodiments, such actions can proceed effectively without necessarily consuming active power.
