ABSTRACT:
In an electronic circuit having a reference voltage generator, a device is provided to stabilize the reference voltage against operating temperature variations. Temperature insensitivity is achieved by interposing a source follower type circuit, having a fuse programmable variable resistance feedback loop, between the generator and the circuitry using the reference voltage level. The present invention is particularly suitable for integrated circuits which employs a single reference potential generating circuit device.
