I simulated the starup of bandgap reference with a PWL source which ramp from 0 to vdd, and get a ripple(spike) about 400mv at the stable point.(stabe Vref=1.25v, the spike is 1.65v).
1) Why the ripple happen and does it mean any problem in my starup circuit?
How can i eliminate it if i can?
2)The rise time may be several ns ,seneral us, even several ms, Which one is the best?
Thanks
