Abstract
A comparison device includes an MSB voltage generation circuit that includes a control signal terminal to generate an MSB voltage; a comparison circuit including a first input terminal receiving a first input signal and a second input terminal receiving a second input signal modified by the MSB voltage outputted from the MSB voltage generation circuit to move to a desired voltage range by comparing the first input signal with the modified second input signal to output an MSB comparison result signal, the comparison circuit, after the first input signal has reached the desired voltage range, comparing the first input signal with a residue voltage and outputting an LSB comparison result signal; and a control circuit receiving the comparison signal and operable to detect a crossing of the first input signal and the second input signal according to the MSB comparison result signal and to output the MSB voltage control signal.
