A semiconductor apparatus comprising:
- a receiver configured to generate an output signal by amplifying an input signal received through a channel, and compensate distortion of the input signal based on a control signal preset according to a voltage level of the input signal;
- and
- an internal circuit configured to operate in response to the output signal,
- wherein the receiver is configured to determine a level of an equalizer driving signal by selecting at least one of a plurality of bias voltages based on the control signal, and
- wherein the receiver includes:
- an amplifying unit configured to generate the output signal by detecting and amplifying a difference between the input signal and a reference voltage;
- a delay unit configured to delay the output signal of the amplifying unit and generate a feedback signal;
- and
- an equalizer circuit configured to control a current sink amount in response to the equalizer driving signal when the feedback signal is input, thereby equalizing the input signal with the reference voltage, and
- wherein the equalizer driving signal is generated based on the control signal and the plurality of bias voltages.
