Receiver circuit with de-emphasis function

摘要

A receiver circuit includes a first differential amplification unit including a variable load section, and configured to receive first and second input signals, and to generate first and second output signals, which are amplified based on an impedance value of the variable load section and a voltage difference between the first and second input signals, a second differential amplification unit configured to receive the first and second output signals and to generate a third output signal based on a voltage difference between the first and second output signals, and a signal generating unit configured to generate an equalization signal for controlling the variable load section based on the third output signal.
