Patent ID: 7368956

Claim:
A data slicer with a source-degeneration structure, comprising: a common-source unit with a source-degeneration resistor, for providing an input signal and producing a reference voltage of the input signal, wherein the common-source unit with the source-degeneration resistor has two input ports and two output ports, the first input port being used for inputting a signal, the first output port connecting a resistor and a capacitor in parallel to obtain a reference voltage; a comparator unit, connecting to the common-source unit with the source-degeneration resistor, the reference voltage of the input signal being provided to the comparator unit, the comparator unit comparing the input signal and the reference voltage of the input signal, and outputs a square-wave signal corresponding to the input signal; and a hysteresis unit for reducing a jitter caused by a high frequency signal loaded on the input signal.
