==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.

==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.
