Abstract
A receiver circuit with input common mode voltage sensing is provided. The receiver circuit is applied to a controller area network and comprises a resistor assembly, connected with a high end and a low end of the controller area network, a common mode voltage sensor and a receiving amplifier. The resistor assembly bucks voltage, respectively generating the high end and low end voltage divisions at first and second nodes and outputting the voltage divisions to the receiving amplifier to generate a resultant signal to an output end of the controller area network. The common mode voltage sensor is connected between the resistor assembly and the receiving amplifier, and able to sense the common mode voltage on bus and control the voltage on center tap of the resistor assembly so the receiver circuit for controller area network can receive the differential signal with a much wider input common mode range.
