Beschreibung
Zusammenfassung:	A tyre pressure measurement system (TPMS) comprises a capacitor and an integrated circuit arranged to receive a supply voltage. The integrated circuit comprises a voltage regulator and a measurement unit The voltage regulator is arranged to be turned on and off for predetermined periods of time such that the capacitor is charged and discharged, respectively. The voltage regulator and the capacitor are connected to the measurement unit in order to selectively provide, in use, electric charge at a voltage between predetermined upper and lower limits,
