Abstract:

An example apparatus can be a low voltage bandgap circuit that includes a bandgap core portion. The bandgap core portion includes an operational amplifier (op-amp). The op-amp includes a PMOS input and an NMOS input. Further, the op-amp is a folded cascode op-amp. The bandgap core portion further includes a first diode coupled to the op-amp. The bandgap core portion further includes a second diode coupled to the op-amp through a resistor.
