Latest Patents

Mark Appel holds a patent for a "Self-compensating digital-to-analog converter and methods of calibration and operation thereof." This invention presents cost-effective structures and methods that enable an integrated digital-to-analog converter (DAC) to achieve wide dynamic ranges and bandwidths. The technology incorporates built-in measurement and compensation mechanisms that are primarily digital. The DAC's distortions are measured using a relatively simple analog-to-digital converter (ADC), which, while not designed for the combination of bandwidth and resolution offered by the DAC, is sufficient for determining the characteristics of the DAC's impairments during calibration. This information is utilized in a feed-forward compensation system during the DAC's normal operation to estimate and cancel distortions in its output signal.
