Abstract
Systems and techniques for performing binary divarication digital-to-analog conversion are described. A described converter includes voltage range adjusters arranged in series to convert a digital sequence to an analog representation, each of the adjusters being responsive to a respective bit of the digital sequence, and a combiner. The first adjuster produces first high and low output voltages based on first high and low input voltages and a most significant bit value of the digital sequence. The last adjuster produces last high and low output voltages based on last high and low input voltages and a least significant bit value of the digital sequence. The last high and low input voltages are responsive to the first high and low output voltages as modified by any of zero or more intermediate voltage range adjusters. The combiner produces an analog output signal based on the last high and low output voltages.
