Title of Invention	A METHOD AND SYSTEM FOR INPUT VOLTAGE DROOP COMPENSATION IN VIDEO/GRAPHICS FRONT-ENDS
Abstract	Methods and systems for input voltage droop compensation in video/ graphics front-end systems. The method of an embodiment of the invention captUres input voltage information supplied to an Analog-to-Digital Converter (ADC) operatively coupled to a bypass capacitor in a video/graphics front-end system; calculates a droop in the input voltage in ADC due to a charge sharing between an input sampling capacitor of the ADC and the bypass capacitor; and compensates for the value of the bypass capacitor using an output of the ADC. Embodiments of the invention provide an improved freedom in the choice of off-chip bypass capacitance in video/ graphics front-end systems.
