Abstract
A digital/analog converter (DAC) includes a reference current generator including an internal resistor, and configured to generate reference current according to a resistance value of the internal resistor and a reference voltage, a digital gain block configured to generate a calibrated digital input signal that is obtained by adjusting a digital gain of a digital input signal based on a ratio between a reference resistance value and a resistance value of the internal resistor, and a conversion circuit configured to convert the calibrated digital input signal into an analog output signal, based on the reference current.
