how to simulate this bandgap

[lokay]

this bandgap is the classic structure, but we use the chopper-stablized OP.
How to do the temperature, vdd sweep?
pls help me , thx so much.

You have to do PSS (Periodic Steady-State) analysis if you have to do temperature sweep simulations. Also, to check stability, you have to do PSS and PAC (instead of conventional DC-AC simulations). For this you need Spectre-RF license, can not be done with spectre.
