Abstract
Circuits and methods for reducing noise in the power supply of circuits coupled to a bidirectional bus are presented. The circuits and methods are responsive to an idle condition on the bidirectional bus. The control signal is applied to and changes an electrical characteristic within the receiver to generate a voltage offset. The voltage offset prevents unintended voltage transitions in the power supply of circuits coupled to the bidirectional bus from generating a signal transition on an output signal connection of the receiver.
