摘要

An electronic circuit (CE) is provided with an oscillator (OSC1) outputting a signal (S1) with a frequency (F1) varying as a function of the temperature (Tc) of this circuit, and receiving or outputting a signal (S2) with a fixed and known frequency (F2). This circuit includes a measurement module (MSR) outputting a measurement signal (Φ1) representative of the variable frequency (F1) evaluated using the fixed frequency signal (S2) used as a reference or standard, and a conversion module (CVRS) applying a transfer function (u−1, v−1, or w−1) that is the inverse of the function for the variation of the frequency of the first signal (S1) as a function of the temperature, to the measurement signal (Φ1), in order to output a signal (Φc) representative of the circuit temperature (Tc).
