Abstract
The present application relates to a sub-bandgap reference source circuit, which comprises a current mirror source, a first branch comprising a first BJT and a second branch comprising a second BJT, the first BJT having an emitter current density lower than an emitter current density of the second BJT, the first branch and the second branch being connected at a first node coupled to ground; a first voltage divider comprising first and second resistances coupled in series, the first resistance being coupled between a base terminal of the first BJT and a second node, the second resistor being coupled to ground; a second voltage divider comprising first and second resistances coupled in series, the first resistance being coupled between the second node and a base terminal of the second BJT, the second resistance being coupled to the first node; and an output terminal coupled to the second node.
