SYSTEM FOR CALIBRATING A TIME CONSTANT OF AN INTEGRATED CIRCUIT, AND INTEGRATED CIRCUIT PROVIDED WITH SUCH A SYSTEM.

摘要

System and method for calibrating a time constant RoC1 of an integrated electronic circuit (1). A variable-impedance filter (20) is coupled at the input of the integrated electronic circuit (1), an analogue input signal V1n of fixed frequency is applied to the filter (20), the analogue input signal V1n attenuation engendered by the filter (20) is measured, and the value of the time constant RoC1 and the value of the impedance of the variable-impedance filter (20) are modified until an attenuation corresponding to the desired attenuation for the integrated electronic circuit is obtained (1).
