Abstract
A method and system for capacitor based digital to analog converter design layout for high speed analog to digital converter are provided. The method includes arranging a plurality of metal plates to form the capacitor. Each of the plurality of metal plates includes a driven plate and a common plate. The method also includes generating a plurality of interconnects in the common plate and extending the driven plate over the plurality of interconnects. Further, the method includes shielding the common plate by the driven plate. The system includes an analog to digital converter. The analog to digital converter also includes capacitor based digital to analog converter and digital logic for controlling digital operations in the analog to digital converter. The capacitor based digital to analog converter includes a plurality of capacitors, and a comparator for comparing the analog output from the digital to analog converter with a ground potential.
