摘要： In one embodiment the present invention includes a method of generating an oscillating signal at different frequencies. The method comprises configuring a digitally controlled oscillator (DCO). The DCO is configured to generate the oscillating signal at a first frequency, and the DCO is configured to generate the oscillating signal at a second frequency. Additionally, the DCO is configured to transition from the first frequency to the second frequency during a transition time period. During the transition time period, the DCO activates the second frequency and deactivates the first frequency during a plurality of time intervals. The time intervals for activating the second frequency and deactivating the first frequency successively increase from the beginning of the transition time period to the end of the transition time period.

摘要： Embodiments described herein provide circuitry employing an inductor having enhanced circuit area usage. The circuitry includes an inductor having a first loop and a second loop adjoining the first loop to form a figure-eight configuration. The circuitry further includes a circuit component disposed at least partially inside an area defined by at least one of the first loop and the second loop. The inductor has an intersection portion between the first loop and the second loop. An input node is located proximate to the intersection portion, the input node having a first extension disposed inside the first loop. An output node is located proximate to the intersection portion. The output node has a second extension disposed inside the second loop. At least a first capacitor is coupled to the input node and the second extension, and at least a second capacitor coupled to the output node and the first extension.

摘要： A method of adjusting signal processing in a receiver based on signal strength includes determining a received signal strength indicator (RSSI) level, defining an RSSI value to be high when the RSSI level is above a first threshold or defining the RSSI value to be low when the RSSI level is below the first threshold, determining an automatic gain control (AGC) gain level, defining an AGC value to be high when the AGC gain level is above a second threshold or defining the AGC value to be low when the AGC gain level is below the second threshold, and adjusting power consumption of one or more receiver stages based on the RSSI value and the AGC value.
