high psrr bandgap
Dear all
I have some question about this bandgap, which is reference from "A Supply-Noise-Insensitive CMOS PLL With a Voltage Regulator Using DC-DC Capacitive Convertor" by Chang-Hyeon Lee,..
In this paper, no detail description about how it works, and only mention RC filter to filte supply noise, and simple start up.
my question is: What is the role of M1, M2, and M13? Can somebody help me to solve it?
