Wireless Circuitry with Delay Measurement and Tuning - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240088924 titled 'Wireless Circuitry with Delay Measurement and Tuning
Simplified Explanation
The patent application describes a wireless circuitry system that includes a processor, upconversion circuit, amplifier, tunable delay circuit, feedback receiver, and delay error measurement circuit.
- The processor generates a baseband signal.
- The upconversion circuit upconverts the baseband signal to a radio-frequency signal.
- The amplifier amplifies the radio-frequency signal.
- The tunable delay circuit selectively delays generation of the radio-frequency signal or another signal intended for the amplifier.
- The tunable delay circuit is controlled using a closed-loop delay adaptation scheme.
- The feedback receiver generates a demodulated signal from the output of the amplifier.
- The delay error measurement circuit detects peaks in the demodulated signal, computes asymmetry in the detected peaks, and outputs a signal to control the tunable delay circuit.
Potential Applications: - Wireless communication systems - Radio frequency transmitters - Signal processing technologies
Problems Solved: - Improving signal processing efficiency - Enhancing wireless communication performance
Benefits: - Increased signal quality - Enhanced control over signal transmission - Improved overall system performance

Unanswered Questions: 1. How does the closed-loop delay adaptation scheme improve the performance of the tunable delay circuit? 2. What specific threshold level is used to detect peaks in the demodulated signal by the delay error measurement circuit?
Original Abstract Submitted
wireless circuitry can include a processor that generates a baseband signal, an upconversion circuit that upconverts the baseband signals to a radio-frequency signal, and an amplifier that amplifies the radio-frequency signal. a tunable delay circuit can be used to selectively delay generation of the radio-frequency signal or to delay generation of another signal intended for the radio-frequency amplifier. the tunable delay circuit can be controlled using a closed-loop delay adaptation scheme. a feedback receiver that is coupled to an output of the amplifier can be used to generate a demodulated signal. a delay error measurement circuit can be used to receive the demodulated signal, to detect a peak by monitoring when an envelope of the demodulated signal crosses a threshold level, to compute an amount of asymmetry in the detected peak, and to output a signal that is used to control the tunable delay circuit.
