  • Patent number: 11239851
    Abstract: A system has a digital-to-analog converter; a reference signal coupled to the digital-to-analog converter; a differential amplifier for applying gain, and for generating output signals as a function of sampled input signals, the reference signal, digital codes, and the gain applied by the differential amplifier coupled to the digital-to-analog converter; and a multi-bit successive-approximation register for determining the digital codes in successive stages coupled to the differential amplifier; and the gain applied by the differential amplifier is corrected based on previously determined digital codes.

  • Patent number: 10484001
    Abstract: A system for digitizing a sampled input value includes a digital-to-analog converter for generating an output signal as a function of (1) the sampled input value, (2) a reference value, and (3) digital codes, and a multi-bit analog-to-digital converter for determining the digital codes in first, intermediate, and subsequent cycles. Dither is dynamically added to the digital-to-analog converter in the intermediate cycle. The dither is corrected for in the subsequent cycle.

  • Patent number: 10038453
    Abstract: An analog-to-digital converter includes a comparator, a capacitive digital-to-analog converter (DAC), and calibration circuitry. The capacitive DAC is coupled to the comparator, and includes a plurality of capacitors. The calibration circuitry is configured to adjust a value of each of the capacitors, and includes binary search circuitry and error correction circuitry. The binary search circuitry applies a binary search over a first number of bits of a multi-bit adjustment value used to adjust the value of one of the capacitors, and averages a first number of comparator output samples to determine each of the first number of bits. The error correction circuitry applies an error correction to the multi-bit adjustment value generated by the binary search, and averages a second number of comparator output samples for the error correction. The second number of comparator output samples is greater than the first number of comparator output samples.
