Abstract
A sensor package includes a first die having a capacitor sensor that includes an active sensing portion and a shield surrounding the active sensing portion. The sensor package further includes a second die that includes a voltage regulator configured to produce a shield voltage and a compensation circuit configured to produce a compensation signal. The voltage regulator and the compensation circuit are electrically coupled to the shield. The voltage regulator is configured to regulate the shield to the shield voltage and the compensation signal produced by the compensation circuit is configured to reduce an interference signal on the shield voltage. The compensation circuit includes one or more coupling capacitors that may be programmable capacitor arrays and calibration methodology entails selecting capacitance values for the programmable capacitor arrays that minimizes the error on an output signal of the sensor package.
