  • Patent number: 10833723
    Abstract: The representative embodiments discussed in the present disclosure relate to techniques in which isolation between transmission signals and received signals in a transceiver may be maintained during downlink carrier aggregation. More specifically, in some embodiments, the transceiver may be implemented to include an electrical balance duplexer that isolates a signal component of a signal transmitted via the transceiver from a receiver signal path of the transceiver. The transceiver may also include analog interference cancellation circuitry implemented to isolate a noise component of the signal transmitted via the transceiver from the receiver signal path (e.g., from one or more downlink receiver channels). As such, the transceiver may operate using inter-band, non-contiguous downlink carrier aggregation, intra-band, non-contiguous downlink carrier aggregation, intra-band, contiguous carrier aggregation, and/or the like.

    Abstract: Systems and methods are provided for improving the operation of a computer or other electronic device that utilizes root-mean-square (RMS) measurements, e.g., RMS current measurements, by reducing error in the RMS measurement. A series of measurement samples are received at a processor, which executes a noise-decorrelated RMS algorithm including: calculating a current-squared value for each measurement sample by multiplying the measurement sample by a prior measurement sample in the series (rather by simply squaring each measurement sample as in conventional techniques), summing the current-squared values, and calculating an RMS value based on the summed values. The processor may also execute a frequency-dependent magnitude correction filter to correct for frequency-dependent attenuation associated with the noise-decorrelated RMS algorithm.

  • Patent number: 10505513
    Abstract: The invention relates to a filter circuit which, on the hardware level, prevents charge transfers caused by one or more currents in a frequency divider (200) from generating an interference signal that can cause a signal distortion at the output of a current-to-voltage converter (300) belonging to a filter circuit. This signal distortion would otherwise have to be removed by means of laborious post-processing of the signal. In this process, the voltage curve at the input of the frequency divider (200) or the current at the second output of the frequency divider (200) are employed so that, by means of a compensation circuit arrangement, it is possible to model a compensation signal that essentially compensates for an interference signal caused by the charge transfers. The invention also relates to an associated method.

  • Patent number: 10418717
    Abstract: The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. By applying a variable reactance (capacitive or inductive component) antenna aperture tuner within a simple, scalar antenna aperture tuning system, the maintenance of a constant antenna resonant frequency in the presence of environmental changes or head/hand effects is obtained. The variable reactance is used to adjust the resonant frequency of the antenna to stay at the desired target frequency in response to external variables that would otherwise shift the resonance away from the operating frequency of the device. Adjusting the resonant frequency of the antenna in response to externally induced changes maintains the radiating efficiency of the antenna and simultaneously avoids impedance mismatch between the antenna and the respective transmit/receive path in the radio, thereby minimizing transmission losses.

    Abstract: A coaxial radio frequency (RF) isolator is disclosed. The isolator includes a first connector that conducts an RF signal received from a first device connected to the isolator. The isolator also includes a conductive body including a second connector and a conductive outer shield that form a first internal cavity. The isolator further includes a dielectric sleeve between the outer shield and the conductive body. In addition, the isolator includes a conductive coupling/filtering member inside the outer shield and the dielectric sleeve. The conductive coupling/filtering member has a cylindrical shape forming a second internal cavity. Moreover, the isolator includes a thru-RF signal transmission path through the first internal cavity and the second internal cavity. The thru-RF signal transmission path receives the RF signal from the first device, conditions the RF signal, and outputs the RF signal to a second device.

  • Patent number: 10355661
    Abstract: A power delivery network, circuit, and method reduce die package resonance of an integrated circuit (IC) die. Decoupling capacitors interact with equivalent series inductances (ESLs) of power conductors within a package carrier substrate create the die package resonance characteristic. In one form, an anti-resonance tuning circuit has a first node conductively coupled to one of the IC die's positive or negative power supply conductors, and a second node conductively coupled directly to a selected conductive structure on the carrier substrate. The anti-resonance tuning circuit includes a tuning capacitor, a tuning inductor, and optionally a dampening resistor coupled in series and having values sufficient to mitigate the die package resonance. In another form, impedance adjustment techniques are provided to connect and tune the anti-resonance tuning circuit to lower an impedance peak.

  • Patent number: 10263591
    Abstract: A device and method for reducing ground currents and electromagnetic interference in pulsed signal devices are described. In one embodiment, the device may include, in addition to regular filtering components and circuits, a separate noise-suppressing choke in the ground wire to reduce current in the ground wire that causes damage to bearings and electrical overstress. Such choke may be of a saturation type that offers high inductance and good noise-blocking properties in normal operating conditions and sufficiently low impedance at fail currents which provides proper tripping of safety circuits.

  • Patent number: 10211496
    Abstract: The present invention provides a common-mode signal absorber, which comprises an impedance-matching network and a common-mode signal reflection circuit. A differential-mode signal is inputted into input ends of the impedance-matching network, and outputted from output ends of the common-mode signal reflection circuit. When a common-mode signal is inputted into the common-mode signal absorber, the common-mode signal reflection circuit is for reflecting the common-mode signal within a specific frequency band. Afterward, the reflection of the common-mode signal within the specific frequency band will be absorbed by an impedance element of the impedance-matching network. Thus, the common-mode signal within the specific frequency band may be absorbed by the impedance-matching network so as to avoid to interfere signals transmitted on a communication system.

  • Patent number: 10177674
    Abstract: Even when a grounding capacitor is included at either end of a common mode coil, there is noise that flows from a load into a metal frame, and there is a need to restrict an amount of noise propagating to a system power supply. Because of this, a noise loop is formed of a rectifier circuit, an inverter, a first electrical wire that connects a positive polarity side of the rectifier circuit and the inverter, a second electrical wire that connects a negative polarity side of the rectifier circuit and the inverter, a ground wire terminal that can connect a load connected to an output terminal or the inverter, and a conductive plate that connects at least one or the first electrical wire and second electrical wire and the ground wire terminal.
