The proposed 1.5-bit/cycle technique with built-in capacitive digital-to-analog converter (CDAC) redundancy, corrects multiple erroneous decisions in a total of nine conversion cycles. The proposed binary-scaled redundancy provides a 12.5% error tolerance range for the incomplete CDAC voltage settling. The digital error-correction logic circuit presented uses a bit-overlap-and-add technique. The prototype chip was fabricated in 65-nm CMOS technology and occupies chip area of 0.038 mm 2 . It consumes 4.06 mW from a 1.2 V supply, achieving the Nyquist signal-to-noise-and-distortion ratio of 57.81 dB and the effective number of bits of 9.31-bit at an operating frequency of 150 MS/s, corresponding to the figure-of-merit of 42.6 fJ/ conversion-step.||URI:||https://hdl.handle.net/10356/92451
