Abstract: An apparatus adapted to convert an input analog signal (In) to an output digital signal (OUT) is described. The apparatus comprises means (1) adapted to convert a first digital value (d(IN1)) of the output signal of the apparatus (100) to a first analog value (IN1), said first digital value (d(IN1)) being emitted by the apparatus at a first time instant, and means for feeding back the first analog value (IN1) to the input of the apparatus. The apparatus (100) comprises first means (2, 3) adapted to determine the difference (Diff) between the first analog value (IN1) and a second analog value (IN) of the input signal of the apparatus at a second time instant successive to the first time instant, second means (4) adapted to convert said difference (Diff) to a digital value (d(Diff)) and third means (5) adapted to add or subtract said digital value (d(Diff)) of said difference to or from said first digital value (d(IN1)) by obtaining said output digital signal (OUT).

Abstract: Described herein is a device for driving a converter circuit that supplies a charge via a first electronic switch (LS) and a second electronic switch (HS) alternately turned on and off, with a first dead-time interval between turning-off of the first electronic switch and turning-on of the second electronic switch (HS) and a second dead-time interval between turning-off of the second electronic switch (HS) and turning-on of the first electronic switch. Turning-off of the second electronic switch (HS) is controlled as a function of a feedback signal (F) coming from the load (L). The device comprises:
- a generator module (11a, C) for generating a memory signal (V c ), indicating the duration of the first dead-time interval; and
- a delay module (11b, C, 14, 18, 20), sensitive to said memory signal (V c ) for controlling turning-on of the first electronic switch with a delay, with respect to turning-off of the second electronic switch (HS), identified by the aforesaid memory signal (V C ), so that the second dead-time interval has a duration substantially equal to the duration of the first dead-time interval.
