A method of measuring and regulating a time constant ( tau ) of an electronic circuit (2) having resistive (7) and capacitive components defining the time constant on the basis of respective resistance (R) and capacitance (C) values. The method includes the steps of forming at least one resistive (7) or capacitive (11, 13, 14, 15, 16) component of adjustable value; measuring the value of the time constant of the circuit (2) by determining at least one error parameter (Ke) related to the error between the nominal value of the time constant and the real value of the measured time constant; and modifying the value of the component of adjustable value on the basis of the error parameter (Ke) to maintain the time constant of the circuit (2) at a substantially constant value. <IMAGE> <IMAGE> |
