Abstract: A method of calibrating a clock phase and a voltage offset includes receiving an input data signal that is periodically toggled. A clock phase calibration operation is performed based on an up signal and a down signal, such that phases of a plurality of clock signals are adjusted. The up signal and the down signal are generated based on the input data signal, a reference voltage and the plurality of clock signals. A voltage offset calibration operation is performed based on the up signal, the down signal and a first sample data signal, such that a voltage level of the reference voltage is adjusted. The first sample data signal is generated by sampling the input data signal based on one of the plurality of clock signals. The clock phase calibration operation and the voltage offset calibration operation are performed independently of each other and not to overlap with each other.

Abstract: Disclosed is a frequency detector. The frequency detector includes a first flip-flop sampling a clock signal based on a data signal to generate a first signal, a second flip-flop sampling a delayed-phase component of the clock signal based on the data signal or sampling the clock signal based on a delayed-phase component of the data signal to generate a second signal, a third flip-flop generating a third signal representing a polarity of a frequency difference between a data rate of the data signal and a frequency of the clock signal based on the first signal and the second signal, and a delay cell generating the delayed-phase component of the clock signal or the delayed-phase component of the data signal. The delayed-phase component has a delay amount set to a value smaller than about 0.25 UI.
