Abstract
The device for generating a reference current proportional to absolute temperature comprises processing means connected to the terminals of a core and designed to equalize the voltages across the terminals of the core, the core being designed to then be traversed by an internal current proportional to absolute temperature, and an output module designed to deliver to an output terminal the said reference current on the basis of the said internal current; the processing means comprise a self-biased amplifier possessing at least one first stage arranged according to a folded setup and comprising first PMOS transistors arranged in a setup of the common-gate type, and a feedback stage whose input is connected to the output of the amplifier and whose output is connected to the input of the first stage as well as to at least one terminal of the core.
