摘要
提出一种集成于带隙电路中的过温保护电路。该电路结构简单,在正常温度工作情况下不消耗额外功耗,具有低功耗的特性,同时电路不受电源电压变化的影响。电路采用JAZZ0.5umBiCMOS工艺库模型,对电路进行仿真表明,电路对电源电压变化的抑制能力强、对阈值温度和迟滞温度差的精度高。
A Thermal-shutdown circuit integrated in the bandgap is presented. It has simple structure, no extra power dissipate in normal temperature, and no impact to the power .The circuit is simulated with JAZZ 0.5um Bicmos technology, it has been demonstrated that the circuit has excellent capacity of power rejection and high precision for threshold and hysteresis temperature.
