Abstract: A digital-to-analog converter apparatus includes a digital-to-analog converter, a resistor-capacitor circuit, a quantizer and a controller. The resistor-capacitor circuit includes an operational amplifier, a first capacitor, a second capacitor, a first resistor, a second resistor, a first switch and a second switch. The digital-to-analog converter may generate a plurality of currents. The quantizer may generate a plurality of offset values. The controller may control coupling of the plurality of currents to the operational amplifier.
