发明名称 Method and apparatus for increasing linearity and reducing noise coupling in a digital to analog converter
摘要 A DAC stage having a ground offset switch driver control signal generator, provides greater linearity by preventing rail-to-rail voltage swings of the switch driver signals. In one embodiment of the present invention, a pair of inverting logic gates, coupled between a power rail and a node positively offset from ground, are used to drive the current switches in a DAC stage.
