Abstract:
1. A digital circuit system, comprising: a first registering unit, for receiving and registering digital data; a logic circuit, including at least one logic unit, for performing a logic operation upon the digital data registered by the first registering unit to change a value of the digital data and accordingly generating resulting data; a second registering unit, coupled to the logic circuit, for receiving and registering the resulting data to generate an output data; a multi-phase clock signal generating unit, for generating a plurality of reference clock signals, wherein the reference clock signals comprise different phases; a first selector, coupled to the multi-phase clock signal generating unit, for selecting one of the reference clock signals to output a first clock signal to the first registering unit; and a second selector, coupled to the multi-phase clock signal generating unit, for selecting another of the reference clock signals to output a second clock signal to the second registering unit.
