  • Patent number: 11460515
    Abstract: A circuit includes a voltage comparator with an output, a first input and a second input, the first input being coupled to a first reference voltage terminal. An operational transconductance amplifier has an output coupled to the second input of the voltage comparator, an inverting input coupled to the output of the operational transconductance amplifier, and a non-inverting input coupled to a second reference voltage terminal. A filter capacitor is coupled in series between a power supply terminal and the second input of the voltage comparator.

  • Patent number: 11196419
    Abstract: A voltage level shifter device an input stage and an output stage. The input stage is configured to lower one of the first and second output terminals to the low level according to the level of the input voltage. A latch circuit includes a first branch having a first PMOS transistor and a second PMOS transistor coupled in series coupled between a shifted-high-level voltage supply terminal and the first output terminal and a second branch having a third PMOS transistor an a fourth PMOS transistor coupled in series between the shifted-high-level voltage supply terminal and the second output terminal. The first output terminal is a gate of the second PMOS transistor and to a gate of the third PMOS transistor. The second output terminal is coupled a gate of the fourth PMOS transistor and to a gate of the first PMOS transistor.

  • Publication number: 20120049812
    Abstract: A switched-mode converter includes first and second chopper transistors, and control means for maintaining the first and second chopper transistors respectively on and off during first operating phases. The first and second chopper transistors are maintained respectively off and on during second operating phases. An intermediary voltage is applied to the gate of the second transistor during intermediary phases taking place between the first and second phases. This intermediary voltage is close to the threshold voltage of the second transistor.

  • Publication number: 20080205095
    Abstract: Systems and methods for compensating ripple current and improved ripple compensators and switching converters capable of compensating ripple current. In one embodiment, the ripple compensator for a switching converter of the type includes a switching means and filtering means comprises means for injecting a compensating current such that the AC component of the switching current and the compensating current are in opposite phase. In addition, the compensation current is elaborated from a signal at a node between the switching means and the filtering means.
