Equalizer and transmitter including the same

An equalizer comprising:

• a delay circuit configured to generate one or more delay signals based on at least one input signal;
• an encoding circuit configured to generate a plurality of driving signals and one or more connection switching signals based on the input signal and the one or more delay signals;
• a pre-driver configured to generate a plurality of driving switching signals based on the plurality of driving signals;
• a first differential circuit configured to generate a first differential output signal based on the plurality of driving switching signals;
• a second differential circuit configured to generate a second differential output signal based on the plurality of driving switching signals;
• and
• a connection circuit configured to adjust a connection between the first differential circuit and the second differential circuit based on the one or more connection switching signals.

A transmitter for transmitting an input signal through a channel, the transmitter comprising:

• a serializer configured to convert the input signal into a serial input signal;
• and
• an equalizer configured to generate a first differential output signal and a second differential output signal based on the serial input signal, the equalizer including,
• a delay circuit configured to generate one or more delay signals based on the serial input signal,
• an encoding circuit configured to generate a plurality of driving signals and one or more connection switching signals based on the serial input signal and the one or more delay signals,
• a pre-driver configured to generate a plurality of driving switching signals based on the plurality of driving signals,
• a first differential circuit configured to generate the first differential output signal based on the plurality of driving switching signals,
• a second differential circuit configured to generate the second differential output signal based on the plurality of driving switching signals, and
• a connection circuit configured to adjust a connection between the first differential circuit and the second differential circuit based on the one or more connection switching signals.
