发明名称 Apparatus for converting an analog signal utilizing resistor D/A converter precharging
摘要 A method for operating a circuit in an analog to digital converter, including providing a resistor network (205) having a plurality of resistor banks (200) connected together, each resistor bank of the plurality of resistor banks having a plurality of resistors (210) connected together in series and a plurality of first switches (220) for selecting a node (215) between adjacent resistors, and a plurality of second switches (235) for selecting a chosen resistor bank of the plurality of resistor banks. A first switch is closed in a chosen resistor bank to charge a parasitic capacitance (250), and a second switch is closed after closing the first switch, and after charging the parasitic capacitance in the chosen resistor bank.
