Abstract

This paper proposes a method of voltage overshoot correction during the load switching-off in the integrated circuits (ICs) where the negative feedback voltage regulators are used. Method uses fictive dynamic load to compensate the fast switching-off process of the actual load. The effect occurs in all regulators where the settling time of voltage regulators is larger compared with the switching time of the actual load. The proposed method gives a chance to the negative feedback regulator to keep the output voltage within a safe range and keep the thin gate low voltage transistors in safe operating mode.
稳压器中的高超调校正方法
提出了一种应用负反馈稳压器的集成电路负载关断时电压超调校正方法。该方法利用有效动态负载来补偿实际负载的快速关断过程。当稳压器的稳定时间大于实际负载的开关时间时,这种效应在所有稳压器中都会发生。该方法使负反馈稳压器有机会将输出电压保持在安全范围内,并使薄栅低压晶体管处于安全工作模式。
