Abstract: Representative implementations of devices and techniques provide analog to digital conversion of time-discrete analog inputs. A redundant binary scaled capacitance arrangement using a successive approximation technique can provide a fast and power efficient ADC, with improved error correction. For example, a successive approximation capacitor arrangement may include multiple arrays of capacitances with binary bit weights. In an implementation, the technique includes processing the capacitances in successive cycles, where each cycle generates a binary error correction code representing greater than one bit of the digital output.
