Abstract
Signals propagating on an aggressor communication channel can cause interference in a victim communication channel. A sensor coupled to the aggressor channel can obtain a sample of the aggressor signal. The sensor can be integrated with or embedded in a system, such as a flex circuit or a circuit board, that comprises the aggressor channel. The sensor can comprise a dedicated conductor or circuit trace that is near an aggressor conductor, a victim conductor, or an EM field associated with the interference. An interference compensation circuit can receive the sample from the sensor. The interference compensation circuit can have at least two operational modes of operation. In the first mode, the circuit can actively generate or output a compensation signal that cancels, corrects, or suppresses the interference. The second mode can be a standby, idle, power-saving, passive, or sleep mode.
