I designed a bandgap reference circuit,as is shown in the attached picture.The circuit is based on the amplifier feedback to build reference voltage.In ac simulation,it's loop gain and phase margin is enough,but in transient simulation,it will fluctuate with amplitude 0.2mV. I dont know which caused it.
Please help me to solve it ,thanks!
