Bandgap Voltage Reference that has 1.2V output with an input VDD of 2.7V~5.5V

[allennlowaton]

Hello EDA fellows,
Can you recommend me a bandgap voltage reference circuit that has 1.2V output and
can properly operate with a VDD from 2.7V to 5.5V?
Any good papers will be highly appreciated.

Thank you.

You can take a look at a few tutorials, maybe they can help

thank you alexan_e.

A shunt reference can be very tolerant of wide swings in the raw
supply, drawback being a limited drive capability. A simple resistor
feed means no voltage division / standoff problems in low voltage
technologies. Of course if you wanted micropower baseline and
mA of drive you'd need a different plan....
