Abstract:
A receiving circuit includes a first capacitor connected to a first signal line, a second capacitor connected to a second signal line. A first bias control circuit may convert a common mode voltage of a first received signal provided through the first capacitor to a first voltage level to output a first biased signal. A second bias control circuit may convert a common mode voltage of a second received signal provided through the second capacitor to a second voltage level to output a second biased signal. A balance compensation circuit may receive the first biased signal and the second biased signal, compensate for an offset voltage of the first biased signal based on the second biased signal, and compensate for an offset voltage of the second biased signal based on the first biased signal to output a first differential signal and a second differential signal.
