  • Input voltage protection system
    Patent number: 4930037
    Abstract: A static electricity protection system for use with a voltage sensitive MOS component having a gate input including a layer of oxide. A transmission gate having a source and a drain as an input and output, respectively, is connected to the MOS component gate input for protecting it from sudden electrical voltage surge discharges. The transmission gate source and drain include a layer of oxide substantially thicker than the oxide layer of the MOS component gate input.
