    摘要: The present disclosure relates to a device comprising an inductive element and a first capacitive element series connected between a first node and a second node, a first MOS transistor connected between the first node and a third node configured to receive a reference potential, the second node being coupled directly or via a second MOS transistor to the third node, a second capacitive element connected between a fourth node and an interconnection node between the first capacitive element and the inductive element, a current generator configured to provide an AC current to the fourth node, and a switch connected between the fourth node and the third node.

    摘要: A PWM signal generator circuit includes a multiphase clock generator that generates a number n of phase-shifted clock phases having the same clock period and being phase shifted by a time corresponding to a fraction 1/n of the clock period. The PWM signal generator circuit determines for each switch-on duration first and second integer numbers, and for each switch-off duration third and fourth integer numbers. The first integer number is indicative of the integer number of clock periods of the switch-on duration and the second integer number is indicative of the integer number of the additional fractions 1/n of the clock period of the switch-on duration. The third integer number is indicative of the integer number of clock periods of the switch-off duration, and the fourth integer number is indicative of the integer number of the additional fractions 1/n of the clock period of the switch-off duration.
