Abstract
A transmitter circuit improves a noise margin for decoding a common mode signal at a receiver circuit. The transmitter circuit includes a common mode signal transmitter and a noise margin enhancement circuit coupled to a transmission line. The common mode signal transmitter transmits a control message using a common mode signal. The common mode signal has a first voltage level and a second voltage level higher than the first voltage level, and the control message corresponds to a portion of the common mode signal having the first voltage level. The noise margin enhancement circuit raises a voltage level of the common mode signal to a third voltage level higher than the second voltage level for a specific time period from a rising edge of the common mode signal from the first voltage level.
