摘要： A system and method is provided for extending the range of a common mode voltage of a differential comparator. In one embodiment, a differential comparator comprises an input stage with a negative voltage reference node, a first differential input coupled to a first differential pair transistor and operative to receive a first input signal, and a second differential input coupled to a second differential pair transistor and operative to receive a second input signal. The first input signal and the second input signal form a differential input signal. The differential comparator further comprises a common mode sensing circuit interconnected between the first differential input, the second differential input, and the negative voltage reference node. The common mode sensing circuit is operative to sense a common mode voltage of the differential input signal and set a voltage potential at the negative voltage reference node substantially equal to the sensed common mode voltage.

摘要： Systems and methods for digital isolation in circuits are provided. On power-up in an isolation application, there may be multiple power supplies. For example, one for an input side and one for an output side, both in relation to an isolation barrier. Upon power up, the input and output may not be at the same state. The bias of the output may be the opposite of what is on the input. An isolator solution is provided which integrates the digital isolation into the analog solution. A DC signal corresponds to the static state of the data at start-up and an AC signal is generated when switching begins. In one example, the output level corresponds to the input level when the steady state information is encoded and sent across as an AC signal.

摘要： 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.
