ABSTRACT:
Systems are provided for reducing electromagnetic emissions from a controller area network transceiver. A driver circuit is operative to transmit communications across an associated bus. A static driver replica circuit approximates a common-mode voltage associated with a dominant state associated with the bus. A receiver attenuator bias circuit forces a common-mode voltage associated with the driver circuit to be equal to the approximated dominant state common-mode voltage during a recessive state associated with the bus.
