Abstract
An apparatus can include a digital-to-analog converter (DAC) and calibration circuitry including an oscillator. The calibration circuitry can be coupled to an output of the DAC, the calibration circuitry to sample and count DAC output pulses for at least two consecutive pulses using at least two separate counter circuits. The calibration circuitry can determine error between at least two consecutive pulses and provide a correction value based on the error. The apparatus can further include correction circuitry to provide a calibration signal to the DAC based on the correction value.
