Claim 5:
6. The electronic ignition system according to claim 1, wherein the integrating circuit comprises an integrating capacitor connected in series to the bias circuit and connected between the bias circuit and the reference voltage, wherein the integrating circuit comprises the connection in parallel of the integrating capacitor and of a Zener diode, the Zener diode having an anode terminal connected to the bias circuit and having a cathode terminal connected towards the reference voltage,
wherein during the phase of measurement of the ionization current the Zener diode is reversely biased and it is configured to limit the voltage across the integrating capacitor during its charging to a maximum defined value equal to the Zener voltage of the Zener diode, and wherein during the phase of transfer of energy the Zener diode is forwardly biased and it is configured to bias the voltage across the integrating capacitor to a substantially null value.
