1、i‘m designing an opa for bandgap,using miller comp tech for getting a PM of around 60. but my nulling resistor has to be around 100k.is it ok for being implemented by CMOS process? as a resistor,it seems to be too large.any other methods to decrease the resistor?
2、opa gain >70db & GBW is about 400KHz,the GBW is ok for bandgap?
ckt is attached here!
