Hi Dan, BGR will be used as refrence in temperature sensor for RFID applications which requires for low power consumption. So, i want to keep it in weak inversion.
I want low offest in the opamp and so weak inversion. I think u have greater current mismatch but less offset in weak inversion.
What type of opamp is best suited for BGR? Is it two stage MIller with grounded capacitor?
Can u suggest me an opamp where Vdd noise directly appears at the output? This ensures Vgs of the PMOS will be Vdd noise resitant since both gate and source will have correlated noise.. in a typical BGR
I am taping out multiple experimental chips. I can take the risk!!!!
Thanks
