It is described an electronic device () for measuring an electric quantity, comprising: an analog-digital conversion module () configured to digitally convert time portions of an analog signal (S(t)) to be measured alternated with time portions of a reference analog signal (S(t)), for supplying respective first (D) and second pluralities (D) of digital values and a digital processing module () configured to: calculate a first mean amplitude (A) of the first pluralities of digital values, and a second mean amplitude (A) of the second pluralities of digital values; the first and second mean amplitudes being proportional to a mean gain value of the analog-digital conversion module (); supply a ratio value (V) of the first mean amplitude to the second mean amplitude, representative of a measured amplitude of the analog signal (S(t)) to be measured.
