Abstract: A circuit includes a digital-to-analog converter (DAC) and a compensation circuit. The DAC has a first terminal and a second terminal. The compensation circuit has a third terminal and a fourth terminal. The third terminal is coupled to the first terminal, and the fourth terminal is coupled to the second terminal. The compensation circuit is configured to source current into the first terminal responsive to an increase in voltage on the second terminal, and to sink current from the first terminal responsive to a decrease in voltage on the second terminal.
