Bandgap Reference Circuit. The circuit generates a variable reference voltage of 1 2380 until 1 3051. What is a bandgap voltage reference.
This particular circuit is one type of a bandgap voltage reference named after paul brokaw the author of its first publication. Abstract this paper describes the design of a programmable voltage bandgap reference simulated in 0 35µm cmos technology. So it can also be used with bipolars in the bcd process to improve robustness.
It commonly has an output voltage around 1 25 v.
The circuit generates a variable reference voltage of 1 2380 until 1 3051. Immunity to supply voltage fluctuations. That means that the voltage reference would ideally be pvt independent. What is a bandgap voltage reference.
