Abstract:
A semiconductor device includes a multilevel receiver including a signal determiner receiving a plurality of multilevel signals and outputting a result of mutual comparison of the plurality of multilevel signals as an N-bit signal, where N is a natural number equal to or greater than 2. A decoder restores a valid signal among the N-bit signals from the signal determiner to an M-bit data signal, where M is a natural number less than N. A clock generator receives a reference clock signal, generates an input clock signal using the reference clock signal, inputs the input clock signal to the signal determiner, and determines a phase of the input clock signal based on an occurrence probability of an invalid signal not restored to the M-bit data signal among the N-bit signals.

The first analog-digital conversion unit is further configured to, during a second analog-digital conversion operation, simultaneously discharge each of the n first differential node pairs, in response to a nth differential signal pair among the n differential signal pairs.
