ABSTRACT:
A buffer circuit device, which receives differential input signals and outputs differential output signals, has a buffer circuit, a common mode level generator circuit, a common mode voltage detection circuit, and a bias voltage adjusting circuit. The buffer circuit receives the input signals and outputs the output signals, and the common mode level generator circuit outputs a specific level of a common mode voltage of the output signals to be output from the buffer circuit. The common mode voltage detection circuit detects a common mode voltage of specific signals, and the bias voltage adjusting circuit adjusts a bias voltage to be supplied to the buffer circuit by comparing an output signal of the common mode level generator circuit with an output signal of the common mode voltage detection circuit.
