Abstract:
An apparatus for converting a capacitance measured on a capacitive sensor to a digital code may include a modulation capacitor to receive charge transferred from the sensor and compensation circuitry to divert charge from the modulation capacitor. A method for operating the apparatus may include generating a digital bitstream based on the capacitance of the sensor and compensating for a parasitic capacitance of the capacitive sensor.
