Abstract
Apparatus and associated methods are disclosed for digital-to-analog conversion with improved performance. In one exemplary embodiment, an apparatus includes a DAC to convert a digital input signal to an analog output signal. The DAC includes a decoder to decode the digital input signal and to provide first and second sets of control signals. The DAC also includes a resistor DAC (RDAC) to provide first and second voltages in response to the first set of control signals. The DAC further includes an interpolator coupled to receive the first and second voltages and to provide a first analog signal in response to the second set of control signals.
