  • Publication number: 20240006994
    Abstract: A DC-DC boost converter includes an input receiving an input voltage and an output producing an output voltage. A switching stage is formed by a low-side transistor arranged between a switching node and a ground node, and a high-side transistor arranged between the switching node and the output. The high-side transistor includes a body diode having an anode coupled to the switching node and a cathode coupled to the output. The converter is controlled in an asynchronous operation mode where the low-side transistor is driven alternately to a conductive state and a non-conductive state, and the high-side transistor is driven steadily to a non-conductive state. A variable load circuit is selectively coupled between the two output terminals when the converter is in the asynchronous operation mode in order to sink a load current having a value that is a function of a value of the input voltage.

  • Patent number: 11862988
    Abstract: A first RF-to-DC circuit receives a radiofrequency signal and produces a first converted signal delivered to an energy storage circuit. A second RF-to-DC circuit, which is a down-scaled replica of the first RF-to-DC circuit, produces a second converted signal from the radiofrequency signal that is indicative of an open-circuit voltage of the first RF-to-DC circuit. The first RF-to-DC section includes N sub-stages, with a sub-set of sub-stages being selectively activatable. A window comparison of the second converted signal generates a first signal and a second signal indicative of whether the second converted signal is within a range of values proportional to a voltage reference signal. The sub-set of sub-stages is selectively deactivated, respectively activated, when the performed window comparison has a first result, respectively, a second result.

    Abstract: In various embodiments, the present disclosure provides semiconductor devices, packages, and methods. In one embodiment, a device includes a die pad, a lead that is spaced apart from the die pad, and an encapsulant on the die pad and the lead. A plurality of cavities extends into at least one of the die pad or the lead to a depth from a surface of the at least one of the die pad or the lead. The depth is within a range from 0.5 ?m to 5 ?m. The encapsulant extends into the plurality of cavities. The cavities facilitate improved adhesion between the die pad or lead and the encapsulant, as the cavities increase a surface area of contact with the encapsulant, and further increase a mechanical interlock with the encapsulant, as the cavities may have a rounded or semi-spherical shape.
