Transmit noise and impedance change mitigation in wired communication system

摘要

Methods and systems are provided for mitigating noise and/or impedance effects in transmitters. The mitigation comprises, when transmitter is in a non-active mode, decoupling at least a portion of the transmitter and coupling an auxiliary component to a remaining portion of the transmitter. When the transmitter is in an active mode, the auxiliary component is decoupled from the remaining portion of the transmitter, and the at least a portion of the transmitter is coupled to the remaining portion of the transmitter. The auxiliary component comprises one or more of: a resistive element, a capacitive element, and a reactive component. The auxiliary component is configured such that it may achieve a small mismatching error.
