20080197861 | METHOD OF AUTOMATICALLY TESTING AN ELECTRONIC CIRCUIT WITH A CAPACITIVE SENSOR AND ELECTRONIC CIRCUIT FOR THE IMPLEMENTATION OF THE SAME - A method for automatically testing an electronic circuit with a capacitive sensor having two capacitors is provided, wherein the common electrode of the capacitors moves relative to each fixed electrode. The electronic circuit includes a sensor interface that includes a charge transfer amplifier unit, an integrator unit connected to the amplifier unit to provide measurement output voltage, and an excitation unit. The excitation unit inversely polarizes each fixed electrode at high or low voltage or discharges the capacitors. The method includes several successive measurement cycles each divided into a first phase discharging capacitors by output voltage and a second phase for polarizing the fixed electrode of the first capacitor at high voltage and inversely polarizing the fixed electrode of the second capacitor at low voltage. In the measuring cycles, a test phase replaces a second polarizing phase in at least one cycle in every two successive measurement cycles. | 08-21-2008 |
