  • Publication number: 20190238146
    Abstract: Wideband polar receivers and method of operation are described. A phase-modulated input signal is received at a polar receiver that includes an injection-locked oscillator. The injection-locked oscillator includes a plurality of injection points. Based on the frequency of the input signal, a particular Nth harmonic is selected, and the input signal is injected at the set of injection points corresponding to the selected Nth harmonic. The injection-locked oscillator generates an oscillator output signal, and the phase of the input signal is determined from the phase of the oscillator output signal. In some embodiments, the oscillator output signal is frequency-multiplied by N, mixed with the input signal, and filtered for use in amplitude detection. The input signal is decoded based on the phase and amplitude information.

  • Patent number: 10326457
    Abstract: Clock generation from an external reference by generating a reference clock gating signal using a reference clock gating circuit; enabling a ring-oscillator-injection mode using the reference clock gating signal to disable a first buffer of a ring oscillator and to enable a reference clock injection buffer, the first buffer and the injection buffer having parallel connected outputs that connect to a next buffer input; receiving a reference clock transition of a reference clock signal at the injection buffer and injecting it into the next buffer; and enabling a ring-oscillator-closed-loop mode by using the reference clock gating signal to enable the first buffer and to disable the reference clock injection buffer.

  • Publication number: 20170131222
    Abstract: The invention relates to a system and method for measuring a physical quantity wirelessly, with a emitter and a passive receiver. On the emitter side, the system comprises an RFID emitter in communication with the RFID receiver. On the receiver side, the system comprises an RFID receiver module, energy storage means supplied by the receiver module, a monitoring module for monitoring the stored energy, a microcontroller module with analog-to-digital conversion means, a measurement module, and an enabling module for enabling the microcontroller module. By means of the monitoring module, the system is adapted to taking periodic measurements only when requested, such that even though peak consumptions are relatively high while taking the measurement, mean consumption remains at values that are low enough to supply the measurement module with the energy stored in the energy storage means without requiring any auxiliary energy source.

  • Patent number: 9497055
    Abstract: Circuitry and methods are described for digital signal demodulation. In a polar receiver, a modulated radio-frequency input signal is provided to frequency division circuitry, which may include a harmonic injection-locked oscillator (ILO). The phase of the frequency-divided output is measured using a self-triggered time-to-digital converter (TDC), which may be a Vernier TDC. A subtractor subtracts a period offset from the output of the TDC to generate an offset digital time output, and a digital integrator integrates the offset digital time output. The integrated time signal represents the phase of the radio-frequency input signal and can be used to determine a symbol, such as a phase-shift keying (PSK) or quadrature amplitude modulation (QAM) symbol, conveyed by the modulated radio-frequency input signal.
