Wireless Circuitry with Delay Measurement and Tuning - A simplified explanation of the abstract
This abstract first appeared for US patent application 17941905 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 the 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.
