Abstract

A system comprising: an electronic circuit exhibiting, in operation, a value v of an operating physical quantity; a measurement device comprising: sensors embedded in the electronic circuit so as to provide raw measurements {X_m} sensitive to the value v of the operating physical quantity, and an output unit for providing useful measurements {X′_n} on the basis of the raw measurements {X_m}; a distribution calculation device for determining a current distribution function F(x) associated with the useful measurements {X′_n}; a memory wherein associations {A_k} are saved, each association A_k associating a model distribution function F_k(x) with a model value v*_k of the operating physical quantity; and an estimation calculation device for determining an estimation {tilde over (v)} of the value v of the operating physical quantity on the basis of the current distribution function F(x) and at least a portion of the saved associations {A_k}.
