Abstract
A method for operating a circuit in an analog to digital converter, including providing a resistor network ( ) having a plurality of resistor banks ( ) connected together, each resistor bank of the plurality of resistor banks having a plurality of resistors ( ) connected together in series and a plurality of first switches ( ) for selecting a node ( ) between adjacent resistors, and a plurality of second switches ( ) 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 ( ), and a second switch is closed after closing the first switch, and after charging the parasitic capacitance in the chosen resistor bank.
