Abstract
An electronic circuit for voltage regulation includes a voltage regulator and a recovery boosting circuit. The recovery boosting circuit is configured to detect a voltage drop occurring in an output voltage of the voltage regulator, to generate (i) a first electrical current that is derived from the output voltage of the voltage regulator and (ii) a second electrical current that is derived from a supply voltage of the voltage regulator, to generate a pulse whose energy depends on the first electrical current and on the second electrical current, and to assist the voltage regulator in recovering from the voltage drop, by applying the pulse to the voltage regulator.
