Abstract
Provided is an offset-voltage calibration circuit. The circuit includes a comparator configured to receive at least two comparison voltages and output a result of a comparison between the comparison voltages, an up/down counter (UDC) configured to output an up-counting or down-counting output signal in response to an output signal of the comparator, and a current digital-to-analog converter (DAC) configured to control the amount of current supplied from a node to which the comparison voltage is applied, in response to the output signal of the UDC and control the magnitude of the comparison voltage.
