Disclosed herein are embodiments of a swing compensation scheme for compensating errors in a transmitter driver.

Transmitter swing control circuit and method

Methods and apparatus relating to dual barrel receiver equalization architectures are described. In an embodiment, a receiver logic may include an amplifier and two comparators to equalize frequency components of a received signal. The receiver logic may further include offset adjustment (or cancelation) logic to generate an offset adjustment (or cancelation) signal coupled to the amplifier. Other embodiments are also described.

Dual barrel receiver equalization architecture

To allow for reference current settings per multi-bit link (or alternatively, per apparatus), approaches for implementing closed-loop Tx swing control based on monitoring of a dummy circuit is provided herein. In accordance with some embodiments, provided is a dummy bit-link circuit to model operable bit-links in a multi-bit link, where each bit link has a transmitter with an adjustable swing level. Also provided is a reference generator circuit to control the transmitter swing levels based on test data driven through the dummy bit-link.
