Abstract
A precision voltage reference incorporating at least one superlattice resonant tunneling diode and support electronics. The precision voltage reference is stable as to temperature and radiation.
Claims18
A superlattice precision voltage reference comprising:
- a host semi-insulating substrate;
- a first layer of doped semiconductor material forming an ohmic contract, on said host semi-insulating substrate;
- a superlattice structure comprising a double barrier system having a layer of smaller band-gap material sandwiched between two layers of larger band-gap material, on said first layer of doped semiconductor material;
- and
- a second layer of doped semiconductor material forming an ohmic contract on said superlattice structure.
