1. A method for supplying power to a transmitter, the method comprising:
performing, during a charging period, a charging process for charging an external capacitor to a charged voltage that exceeds a voltage of a coin cell, wherein the charging process comprises iterations of (a) charging a charge pump capacitor by the coin cell, and (b) discharging the charge pump capacitor to charge the external capacitor; and
during a transmission period, feeding power, under control of a regulator, from the external capacitor to the transmitter;
wherein a capacitance of the charge pump capacitor is less than a capacitance of the external capacitor, and wherein a duration of the charging period exceeds a duration of the transmission period.
