  • Patent number: 11184016
    Abstract: The present disclosure includes a frequency divider circuit that includes a superharmonically injection-locked ring oscillator, injection circuitry, and various switches. The input can include a collection of signal components at different phases that are all at the same, but changeable, frequency. The divider's division ratio can be changed during the divider's operation by, for example, utilizing one or more switches to change: the number of stages in the ring oscillator, and/or which stage(s) of the ring oscillator are injected into by which input signal components.

  • Patent number: 11169556
    Abstract: A first generator produces a first signal that is supplied to an energy storage circuit. Energy transfer circuitry coupled to the energy storage circuit transfers energy stored in the energy storage circuit to an output node. A driver circuit coupled to the energy transfer circuitry switches the energy transfer circuitry between a state where energy from the first signal is stored in the energy storage circuit and a state where energy stored in the energy storage circuit section is delivered to the output node. A voltage at the energy storage circuit varies between an upper value and a lower value around a voltage setting point. A second generator, which is a scaled-down replica of the first generator, produces a second signal that is indicative of an open-circuit voltage of the first generator. The driver circuit uses the second signal to set the voltage setting point.

  • Patent number: 11163181
    Abstract: A method for generating a control signal, having at least one frequency component, for an acousto-optical element, from one frequency spectrum having the at least one frequency, or from multiple frequency spectra which together have the at least one frequency, includes the step of obtaining, from the one frequency spectrum or from the multiple frequency spectra, one transmit signal in the time domain in each case via an inverse Fourier transform. The one or the multiple transmit signals are modulated via a single-sideband modulation onto a carrier signal having a carrier frequency in order to obtain one modulated signal in each case. The control signal is obtained as a real part of the one modulated signal or as a consolidation of the real parts of the multiple modulated signals.

  • Patent number: 11165389
    Abstract: An electronic device may include a transceiver with mixer circuitry that up-converts or down-converts signals based on a voltage-controlled oscillator (VCO) signal. The transceiver circuitry may include first, second, third, and fourth VCOs. Each VCO may include a VCO core that receives a control voltage and an inductor coupled to the VCO core. Fixed linear capacitors may be coupled between the VCO cores. A switching network may be coupled between the VCOs. Control circuitry may place the VCO circuitry in one of four different operating modes and may switch between the operating modes to selectively control current direction in each of the inductors. The VCO circuitry may generate the VCO signal within a respective frequency range in each of the operating modes. The VCO circuitry may exhibit a relatively wide frequency range across all of the operating modes while introducing minimal phase noise to the system.
