Patent abstract
Bandgap reference circuitry comprises a first current mirror connected to a power supply line and configured to supply a first current to a first node and a second current to a second node virtually-shorted to the first node, a first pn junction element between the first node and a ground line; a first variable resistor element between the second node and the ground line, and a second pn junction element connected in series to the first variable resistor element. The first variable resistor element has a resistance dependent on a power supply voltage supplied to the power supply line.
