CMOS process

A high-voltage MOS transistor is produced in a low-voltage CMOS process without adding extra process steps for producing the high-voltage MOS transistor. The high-voltage MOS transistor is to be used as an analog line driver and is produced on the same silicon area as low voltage AD/DA-converters. H...

Zusammenfassung:A high-voltage MOS transistor is produced in a low-voltage CMOS process without adding extra process steps for producing the high-voltage MOS transistor. The high-voltage MOS transistor is to be used as an analog line driver and is produced on the same silicon area as low voltage AD/DA-converters. Hereby, the low-voltage and the high-voltage design block are directly compatible with each other, e.g. have the same threshold voltages, which simplifies the design of the total solution.
