DEFINITION

Classification: 323/313

To derive a voltage reference (e.g., band gap regulator:

(under subclass 312) Subject matter wherein the current within the device is stabilized for the purpose of producing a stabilized reference voltage at its output.

(1) Note. Devices herein generate a reference potential related to an inherent property such as the band gap potential of a semiconductor material such as silicon. The band gap potential is the difference in energy between the energy level of the bottom of the conduction band and the energy level of the top of the valence band.
