Abstract:
1. A method, comprising: communicatively coupling first and second integrated electronic devices together through a reference capacitor and a first coupling capacitor; transmitting a transmission reference signal on a transmission reference electrode of said reference capacitor; receiving a coupling signal on a reception reference electrode of said reference capacitor; amplifying said coupling signal, generating a reception reference signal; generating a reception control signal as a function of said reception reference signal; transmitting a first communication signal on a first transmission electrode of said first coupling capacitor; receiving a first reception signal on a first reception electrode of said first coupling capacitor; amplifying said first reception signal, generating a first compensated signal; controlling a level of amplification in said steps of amplifying said coupling signal and of amplifying said first reception signal as a function of said reception control signal; and detecting a possible misalignment between said first and second integrated electronic devices based on an amplitude of said first communication signal and an amplitude of said first compensated signal.
