Patent ID: 11921533
Assignee: RENESAS ELECTRONICS AMERICA INC.
Field: Control (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A bandgap voltage device comprising:
a first current source operatively coupled to a bandgap input node and a bandgap output node, and operable to output a first proportional-to-absolute-temperature (PTAT) current;
a current mirror including a first bandgap transistor and a second bandgap transistor, and operatively coupled to the bandgap output node; and
a second current source operatively coupled to the current mirror, and operable to output a second PTAT current,
wherein the first bandgap, transistor and the second bandgap transistor each comprise a bipolar junction transistor, and
wherein the bipolar junction transistor comprises a first P+ layer proximate to a center of a planar surface of the transistor device.
