Abstract: An adaptive mode has been added in a common mode (CM) dimmer circuit to increase output current capability only when needed. Without having an adaptive mode in the CM dimmer, the output current drivers must operate with large quiescent current to handle a bulk current injection (BCI) event. Therefore, a CM dimmer without the adaptive mode will consume a significant amount of power even when there is no BCI event occurring. With the adaptive mode, the CM dimmer can be used effectively to suppress the BCI event, e.g., in a transformer-less physical layer (PHY) connection, while consuming minimal power during normal circuit operation.
