Abstract
A digital signal generator includes an input unit configured to receive signal information of a target data signal, a controller configured to calculate at least two delay values and at least two data values, the at least two delay values and the at least two data values being used to generate a data signal corresponding to the signal information input through the input unit, a multi-phase clock generator configured to delay a reference clock signal based on the at least two delay values to generate at least two clock signals having different phases, a signal generator configured to generate at least two data signals by assigning the at least two data values to the at least two clock signals, and a logic gate unit configured to generate the data signal corresponding to the signal information input through the input unit based on the at least two data signals.
