摘要：
A SINGLE DIE SOLUTION OF AN INTEGRATED SENSOR SYSTEM (10) FOR READING SOIL MOISTURE IS DESCRIBED. THE INTEGRATED SENSOR SYSTEM (10) FOR A FRINGING ELECTRIC FIELD SENSOR (12) COMPRISES A READOUT INTERFACE CIRCUIT (14), AND AN ANALOG TO DIGITAL CONVERTER (16). THE SENSOR (12) MEASURES MOISTURE AND CREATES AN ANALOG ELECTRICAL SIGNAL WHICH MATCHES THE MOISTURE LEVEL. THE READOUT INTERFACE CIRCUIT (14) AMPLIFIES THE ANALOG SIGNAL, AND THE ANALOG TO DIGITAL CONVERTER CONVERTS THE ANALOG SIGNAL INTO DIGITAL SIGNAL. THE OUTPUT OF THE INTEGRATED SENSOR PROVIDES A DIGITAL OUTPUT OF MOISTURE READINGS.
