Abstract
A delta-sigma analog-to-digital converter is provided that includes a continuous-time integration stage having an input terminal coupled through a switch to an input resistor that in turn couples to an input signal node. A feedback digital-to-analog converter converts a digital output signal to form a feedback current that also couples to the input terminal. A controller switches the first switch responsive to a duty cycle of the feedback current.
