摘要： RF switching circuitry includes one or more RF switching elements, a control signal input node, a common resistor, and common resistor bypass circuitry. The one or more RF switching elements are coupled in series between a switch input node and a switch output node. A state of each one of the one or more switching elements is determined based on a control signal. The control signal input node is configured to receive the control signal. The common resistor is coupled between the control signal input node and the one or more RF switching elements. The common resistor bypass circuitry is configured to receive the switching control signal and bypass the common resistor for a predetermined time period following one or more of a leading edge of the switching control signal and a falling edge of the switching control signal.

摘要： A circuit includes an electronic component package that comprises at least a first lead, a III-N device in the electronic component package, a gate driver, and a ferrite bead. The III-N device comprises a drain, gate, and source, where the source is coupled to the first lead. The gate driver comprises a first terminal and a second terminal, where the first terminal is coupled to the first lead. The ferrite bead is coupled between the gate of the III-N transistor and the second terminal of the gate driver. When switching, the deleterious effects of the parasitic inductance of the circuit gate loop are mitigated by the ferrite bead.

摘要： In accordance with an embodiment, a method of operating a switched-mode power supply includes controlling a first switch coupled between an inductor and a reference node. Controlling includes modulating a first switching signal to control a first current through the first switch to a first predetermined current, and attenuating a current supplied by the first switch to the inductor in accordance with an attenuation factor to form an attenuated current. Attenuating includes providing a pulse modulated signal to a second switch coupled between the first switch and the inductor, where the attenuation factor is related to a pulse density of the pulse modulated signal.

摘要： A driver device is for switching on and off a transistor for supplying a load by driving a control electrode of the transistor. The driver device includes a first terminal connected to the control electrode of the transistor, a second terminal connected between the transistor and the load, and a current-discharge path coupled to the first terminal. The current-discharge path includes a diode and is activated when the transistor is switched off. The diode becomes non-conductive to interrupt the current-discharge path when the voltage on the second terminal reaches a threshold value.

摘要： An expansion control circuit includes a delay circuit coupled to a first expansion module and a switching circuit coupled to a second expansion module. The switching circuit includes a buffer and a switching module. The buffer is coupled to the first expansion module. The first expansion module outputs a first control signal upon being switched on and outputs a second control signal after a working time. The delay circuit outputs a disconnecting signal upon being switched on. The buffer is switched off upon receiving the disconnect signal. The delay circuit further outputs a connecting signal after a delay time after outputting the disconnecting signal. The buffer is switched on upon receiving the connect signal. The buffer further outputs the second control signal to the switching module upon being switched on. The switching module controls the second expansion module to be switched on v receiving the second control signal.

摘要： A switching unit serves for the arithmetic linking of at least two input signals supplied to the switching unit. For this purpose, the switching unit provides a switching matrix to which the at least two input signals are supplied. The switching matrix applies at least one summation operation to at least two input signals and/or at least one multiplication operation to at least one input signal. Additionally or alternatively, the switching matrix can also connect at least one input signal directly through to a first output. The switching matrix comprises for this purpose several current switches.
