Abstract
A device provides high impedance contact pads for an electrostatic charge sensor. The contact pads are shared between the electrostatic charge sensor and drivers. The contact pads are set to a high impedance state by reducing current leakage through the drivers. Compared to electrostatic charge sensor with low impedance contact pads, the electrostatic charge sensor disclosed herein has high sensitivity, and is able to detect weak electrostatic fields.
