bandgap noise
How to do the noise analysis about Bandgap circuit?
Only measure the PSRR?
Thanks.

paulux said:For PSRR, just add ac signal on top of DC supply voltage.
For noise simulation, use .noise in Hspice simulation.
Break the loop, insert noise source, and do .noise simulation
jcpu, if the temperature changes, the difference between V+ and V- change?, and why?
orley said:if your bandgap include OPA,you must insert noise source in the loop of the bandgap system;but your bandgap only used transistors , you may refer to analysis of noise in transistor at chp.7 of design of analog CMOS integrated circuits by Razavi.
