  • Balanced dual resistor string digital to analog converter system and method
    Patent number: 7259706
    Abstract: A digital to analog converter system is disclosed for receiving an input signal and a sign bit signal that is indicative of the sign of the input signal. The digital to analog converter system includes first and second pairs of resistor strings, and first and second switching networks. A first one of the first pair of resistor strings is adapted for coupling between a first voltage potential and an intermediate node. The first switching network is adapted to couple a voltage produced across a selected one of resistors in the first string across the second one of the resistor strings. The resistors in the second resistor string producing voltages in response to current passing from the first resistor string to the second resistor string through the first switching network. A third one of the second pair of resistor strings is adapted for coupling between a second voltage potential and the intermediate node.
