1. A string digital to analog converter (DAC), comprising:

  • an impedance network comprising a first and second impedance strings;

    a set of switches to couple a first voltage across the first impedance string to the second impedance string in a first code configuration and to couple a second voltage across the first impedance sting to the second impedance string in a second code configuration; and

    a charge boost circuit to inject a boost charge into the impedance network during a transition between the first code configuration and the second code configuration.
