The present invention provides a wireless communication circuitry including a processor, a communication path and a channel detection path. The communication path is configured to wirelessly communicate with an electronic device by using a first channel. The channel detection path is configured to detect at least one channel different from the first channel to generate a detection result while the communication path is wirelessly communicating with the electronic device by using the first channel. The processor determines a second channel based on the detection result, and the processor controls the communication path to switch to the second channel from the first channel to communicate with the electronic device.

Wireless communication circuitry and wireless communication method

A radio frequency front-end receiver includes a single stage low noise amplifier connected with a resistor array and a capacitor array, and a Gilbert-type mixer connected with a PMOS transconductance stage, an inductor and a serially connected current source. The resistor array enables the adjustment of the power gain of the low noise amplifier. The capacitor array tunes the low noise amplifier so that the maximum power gain is at the desired operating frequency. The PMOS transconductance stage reduces the power consumption of the mixer. The inductor increases the impedance and the current source improves the common-mode rejection of the mixer.
