ABSTRACT:
An electrostatic measurement apparatus for generating a modified electrical signal in proportion to an electrostatic potential present on a surface. The apparatus includes a sensor for producing a signal representative of the electrostatic potential on the surface. The apparatus also includes a high-voltage level shifter and a converter to transform the sensor signal into a low-voltage signal indicative of the surface potential. The electrostatic measurement apparatus is implemented using high-voltage and low-voltage integrated circuit technology.
