1. A method for determining position information, the method comprising: selecting a column of a capacitive sensor array; selecting a first row of said capacitive sensor array; selecting a second row of said capacitive sensor array, wherein said first row and said second row intersect with said column of said capacitive sensor array; measuring a differential current between: a current associated with a capacitor of said first row and said column, and another current associated with another capacitor of said second row and said column; measuring a differential capacitance between said first row and said second row, based on the measured differential current, the measuring of the differential capacitance including: converting the measured differential current to a voltage; and generating a digital value based on the voltage, the digital value representing the measured differential capacitance; and determining a location of an object proximate to said capacitive sensor array, based on the measured differential capacitance.
