A Novel Thermal Protection Circuit Based on Bandgap Voltage Reference
Lecture Notes in Electrical Engineering(2016)
摘要
A novel thermal protection circuit based on a bandgap voltage reference is presented in this paper. Simulation was carried out using Cadence Spectre, based on a 0.25 mu m CMOS (Complementary Metal-Oxide-Semiconductor Transistor) process, which indicated that the thermal protection temperature threshold is approximately 130 degrees C. It was also found that the hyteresis is nearly 20 degrees C in all types of process corners, and the designed bandgap reference voltage is 1.205 V with a temperature coefficient of 12.84 ppm/degrees C.
