Abstract

A DUAL-FUNCTION ANALOG TO DIGITAL CONVERTER IS DISCLOSED COMPRISING AN ANALOG FRONT END (104), A FUNCTIONALITY SELECTION CIRCUITRY, A DIGITAL TO ANALOG CONVERTER (102), A COMPARATOR (106), A SUCCESSIVE APPROXIMATION REGISTER LOGIC (112) AND AN OUTPUT REGISTER (114). THE ANALOG FRONT END (104) COUPLES AN INPUT SIGNAL TO THE COMPARATOR (106) FOR EITHER ANALOG TO DIGITAL CONVERSION OR CAPACITANCE TO DIGITAL CONVERSION. THE FUNCTIONALITY SELECTION CIRCUITRY DETERMINES THE INPUT SIGNAL COUPLED TO THE COMPARATOR (106) AS BEING EITHER AN OUTPUT OF THE DIGITAL TO ANALOG CONVERTER (102) OR AN ANALOG INPUT CAPACITANCE SIGNAL. THE DIGITAL TO ANALOG CONVERTER (102) GENERATES A SCALED REFERENCE VOLTAGE REQUIRED BY THE COMPARATOR (106). THE COMPARATOR (106) COMPARES THE INPUT SIGNAL AND THE SCALED REFERENCE VOLTAGE TO GENERATE A COMPARISON RESULT. THE SUCCESSIVE APPROXIMATION REGISTER LOGIC PERFORMS SUCCESSIVE APPROXIMATION BASED ON THE COMPARISON RESULT FROM THE COMPARATOR (106) TO GENERATE EITHER A SCALED OUTPUT REQUIRED BY THE DIGITAL TO ANALOG CONVERTER (102) OR A DIGITAL OUTPUT PROPORTIONAL TO THE INPUT SIGNAL STORED IN THE OUTPUT REGISTER (114).
