Abstract

Integrated power converters suffer from overheating when they operate under extreme conditions. To prevent destructive breakdown an over-temperature protection (OTP) circuit is usually designed along with circuits, which restricts the chip temperature within a threshold level. From a design standpoint, OTP output should vary within a limit range throughout the whole process corners in order to support the chip's reliability. The paper presents an OTP circuit design to limit fluctuations in triggering and reset points by reducing the comparator errors. Simulated results revealed the designed OTP circuit can reach less than 10 % variation over 300 different corners.
