Abstract
A high-voltage differential sensor includes an attenuator formed of two matched monolithic capacitance divider networks. Each divider network is formed of a series connection of monolithically integrated capacitors, which together generate an attenuated differential signal from a high-voltage differential input signal. The attenuated differential signal from the capacitance divider networks is then amplified and fed to a comparator, which generates a first output level when the high-voltage differential input signal is above a selected level, and generates a second output level when the high-voltage differential input signal is below the selected level. By using monolithically integrated capacitors in the divider networks of the attenuator, a simple, compact, low power, high performance high-voltage differential sensor is obtained.
