Receiver with multiple transmission mode settings

Abstract

A receiver includes a termination resistor circuit, a reference voltage generator, a comparator, a filter and a digital circuit. The termination resistor circuit outputs a common-mode voltage in a calibration mode and outputs multiple input signals in multiple transmission modes. The reference voltage generator outputs the common-mode voltage in the calibration mode, and provides multiple reference voltages in the transmission modes. The comparator generates a first signal according to the common-mode voltage and performs an offset calibration in response to an offset calibration signal in the calibration mode, and compares the reference voltages with the input signals to generate the first signal in the transmission modes. The filter outputs the first signal as an output signal in the calibration mode, and generates the output signals according to the first signal in the transmission modes. The digital circuit generates the offset calibration signal according to the output signal.
