Abstract
A receiving circuit with an ultra-wide common-mode input voltage range applies to a controller area network (CAN) and comprises a resistor assembly electrically connected with a CANH and a CANL, a reference amplifier, a first input amplifier assembly, a second input amplifier assembly, and an analog adder. The receiving circuit receives voltages from the CANH and CANL. The resistor assembly bucks voltage, respectively generating CANH and CANL voltage divisions at first and second nodes and outputting the voltage divisions to the first and second input amplifier assemblies. The first and second input amplifier assemblies amplify the differential signal between the first and second nodes and convert the differential signal into single-end signals. The analog adder adds the single-end signals as the output signal. The receiving circuit can receive the signal ranging between the maximum and minimum common-mode voltages and reduce electromagnetic emission.
