Abstract: The present disclosure provides a vertical inductor structure in which the magnetic field is closed such that the magnetic field of the vertical inductor structure is cancelled in the design direction outside the vertical inductor structure, yielding a small, or substantially zero, coupling factor of the vertical inductor structure. In one embodiment, several vertical inductor structures of the present disclosure can be placed in close proximity to create small resonant circuits and filter chains.

Abstract: This disclosure relates to hybrid couplers for radio frequency (RF) signals. The hybrid coupler includes a first port, a second port, a third port, a fourth port, a first inductive element connected from the first port to the third port, and a second inductive element connected from the second port to the fourth port. The hybrid coupler further includes a first capacitive element and a second capacitive element. The first capacitive element is connected between an intermediary node of the first inductive element and either the first port or the third port, while the second capacitive element is coupled between an intermediary node of the second inductive element and either the second port or the fourth port. Accordingly, the first capacitive element and a portion of the first inductive element and the second capacitive element and a portion of the second capacitive element each form a harmonic trap.

Abstract: The present disclosure relates to de-multiplexing at least one RF input signal feeding RF power amplifier circuitry to create multiple de-multiplexed RF output signals, which may be used to provide RF transmit signals in an RF communications system. Output transformer circuitry is coupled to outputs from the RF power amplifier circuitry to provide the de-multiplexed RF output signals, which may support multiple modes, multiple frequency bands, or both. The de-multiplexed RF output signals may be used in place of RF switching elements in certain embodiments. As a result, RF front-end switching circuitry in the RF communications system may be simplified, thereby reducing insertion losses, reducing costs, reducing size, or any combination thereof. Additionally, the output transformer circuitry may provide load line transformation, output transistor biasing, or both to the RF power amplifier circuitry.

Abstract: A bus interface system is disclosed that includes a master bus controller and a slave bus controller that are coupled by a bus line. The slave bus controller includes a decoder that allows for data to be transmitted along just the bus line. The decoder includes an oscillator, a first counter, and a comparison circuit. The oscillator is configured to be enabled by data pulses defined by the input data signal and generate oscillation pulses while enabled. The first counts the oscillation pulses and indicates a number of the oscillation pulses generated during a time slot. The comparison circuit is configured to this number with a reference number and generate a data output that represents a first logical value in response to the number being greater than the reference parameter and represents a second logical value in response to the number being less than the reference parameter.
