Custom CMOS Approach to Automotive Instrumentation

The paper will deal mainly with custom C-MOS approaches to most measurement and warning signal needs of the automobile. It will cover considerations for selection of a technology, possible circuit approaches for system design needs, characteristics of the technologies and variations to be expected with environmental changes. It will consider device and building block characteristics of the technologies along with their variations and discuss environmental protection such as input protection techniques for electrical transients and temperature excursion. Original design custom circuits will be discussed.
