Abstract: A circuit includes a main amplifier having a first input and a first output. A main bias circuit is coupled to the main amplifier, and the main bias circuit configured to operate the main amplifier in a first frequency band. A feedforward cancellation amplifier has a second input and a second output, in which the second input is coupled to the first input, and the second output is coupled to the first output. A filter is coupled between the first input and the second input. A feedforward bias circuit is coupled to the feedforward cancellation amplifier. The feedforward bias circuit is configured to operate the feedforward cancellation amplifier in a second frequency band within and narrower than the first frequency band.

Abstract: An electronic device has a substrate and first and second metallization levels with a resonant circuit. The first metallization level has a first dielectric layer on a side of the substrate, and a first metal layer on the first dielectric layer. The second metallization level has a second dielectric layer on the first dielectric layer and the first metal layer, and a second metal layer on the second dielectric layer. The electronic device includes a first plate in the first metal layer, and a second plate spaced apart from the first plate in the second metal layer to form a capacitor. The electronic device includes a winding in one of the first or second metal layers and coupled to one of the first or second plates in a resonant circuit.

Abstract: In described examples, a method of operating a charge pump includes a first control signal deactivating a first transistor, and the first control signal's logical complement activating a second transistor to reset the first transistor's DC bias voltage. The first control signal's logical complement deactivates the second transistor, and the first control signal provides a bias voltage to the first transistor to activate it, causing current to be transmitted from an input voltage to an output terminal. A second control signal deactivates a third transistor, and the second control signal's logical complement activates a fourth transistor to reset the second transistor's DC bias voltage. The second control signal's logical complement deactivates the fourth transistor, and the second control signal provides a bias voltage to the third transistor to activate it, causing current to be transmitted from the output terminal to a ground.

Abstract: An antenna integrated in a device package is formed such that at least a portion of the antenna is elevated with respect to a substrate of the device package. The entire antenna and its functionality are positioned within a space extending vertically upwardly from a footprint of the substrate that contains circuitry of the device. The boundary of the space is defined by the perimeter of an over mold positioned on the substrate and encapsulating the circuitry.

Abstract: In described examples of a signal equalizer, a first filter stage is configured to perform adaptive equalization of crosstalk between a first signal component and a second signal component of a complex signal. A second filter stage is coupled serially to the first filter stage. The second equalizer stage is configured to perform separate adaptive equalization of the first signal component and separate adaptive equalization of the second signal component

Abstract: A track and hold circuit includes a signal input terminal, a clock input terminal, an output terminal, a transistor, and a bootstrapping circuit with a transformer. The transistor includes a source, a drain, and a gate, where the source is coupled to the signal input terminal, and the drain is coupled to the output terminal. The transformer includes a primary winding coupled to the clock input terminal, and a secondary winding. The secondary winding is coupled between the source and the gate to control a gate-source voltage of the transistor.

Abstract: A system is provided in which a first waveguide has a first resonator coupled to an end of the first waveguide. A second waveguide has a second resonator coupled to the second waveguide. The first resonator is spaced apart from the second resonator by a gap distance. Transmission of a signal propagated by the first waveguide across the gap to the second waveguide is enhanced by a confined near field mode magnetic field produced by the first resonator in response to the propagating wave that is coupled to the second resonator.

Abstract: Described examples include an integrated circuit including a receive portion to receive an encoded transmission on a line. The receive portion has: a wake mode in which the receiver is capable of receiving the encoded transmission; and a sleep mode in which the receiver is not capable of receiving the encoded transmission. A wakeup controller monitors the line for a wakeup signal and provides a signal to the receive portion to cause the receive portion to enter the wake mode when the wakeup controller receives the wakeup signal.
