  • Publication number: 20240014844
    Abstract: The present disclosure discloses a transceiver apparatus having self-calibration mechanism that includes a signal transmission path, a signal receiving path, a path switching circuit, a transceiver circuit and a self-calibration circuit. The path switching circuit includes a switch to switch a connection relation among an antenna, the signal transmission path and the signal receiving path. The transceiver circuit is coupled to the signal transmission path and the signal receiving path. The self-calibration circuit controls the transceiver circuit to transmit a transmission signal through the signal transmission path to the path switching circuit and receives a leakage signal generated according to the transmission signal through the signal receiving path, so as to perform a self-calibration process on the transceiver circuit based on the transmission signal and the leakage signal. The leakage signal has a leakage signal strength larger than a predetermined level.

  • Patent number: 11799423
    Abstract: The application discloses a method, for building an oscillator frequency adjustment lookup table in a transceiver, wherein the transceiver generates a clock according to a crystal oscillator external to the transceiver for transceiving data. The transceiver includes adjustable capacitor arrays assembly connected to the crystal oscillator, wherein when an equivalent capacitance of the adjustable capacitor assembly is a reference value, the crystal oscillator has a reference frequency, and when the equivalent capacitance changes relative to the reference value, the crystal oscillator correspondingly has a frequency offset relative to the reference frequency. The method includes: performing an interpolation operation according to a first value, a second value, and a third value of the equivalent capacitance, and the corresponding frequency variations, so as to obtain the frequency variations corresponding to a first sub-value between the first value and the second values.
