Abstract:
Apparatus and methods are presented for compensating for offsets in digital-to-analog converters (DACs). An apparatus may comprise a gain block. The non-inverting input of the gain block may be provided with a bias voltage selected to exceed the worst-case expected positive offset of a DAC. Feedback from the output of the gain block may be provided to a processor. The processor may be connected to drive the DAC.
