Abstract
In a high-withstand-voltage integrated circuit, several circuits are included at different potentials. Each circuit of a different potential has a power source, and interface circuits mediate signals between the circuits of different potentials. By this design, the required number of high-withstand-voltage elements is reduced, and a low-cost, high-withstand-voltage IC with high integration density, surge tolerance and stability is obtained.
