Circuit Design Techniques for High-Voltage Comparators and Amplifiers

This paper reviews the state-of-the-art technology, circuit architectures, and design strategies commonly used in high-voltage integrated circuits. After a brief discussion about the available technologies and devices, fundamental analog building blocks used in high-voltage applications are introduced. A novel self-protected input stage and various high-voltage tolerant output stages are reviewed. Finally, industry standard high-voltage comparator and amplifier design examples are given.
