Abstract
A method and system for measuring a time constant RC of an integrated electronic circuit is provided. This integrated circuit may be made up of a first hardware component and of a second hardware component wherein one of the hardware components is a resistive element and the other is a capacitive element. The first and the second hardware components are connected to an inverting input of an operational amplifier of an integrator of a delta-sigma modulator. A DC voltage is applied to the modulator input. The output signal Qof the modulator is measured with the aid of an analog/digital converter, and the value of the time constant RC is determined on the basis of at least one measurement of the level of the DC component of the output signal Qof the modulator carried out with the air of a measurement counter circuit.
