ABSTRACT:
A band-gap type constant voltage generating device includes a current source to generate a current increasing linearly as a function of the temperature, and a first current mirror to copy the current in the current source into an "output" leg. The output leg according to the invention comprises at least one junction with a voltage at its terminals that reduces linearly with the temperature, and a load resistance connected in series with the junction. The band-gap type constant voltage generator may be used as voltage reference.
