摘要： Film bulk acoustic resonators (FBARS) have resonant frequencies that vary with manufacturing variations, but tend to be matched when in proximity on an integrated circuit die. FBAR resonant frequency is determined using a fractional-N synthesizer and comparing phase/frequency of an output signal from the fractional-N synthesizer to a reference. The reference may be derived from a low frequency crystal oscillator, an external signal source, or a communications signal.

摘要翻译：薄膜体声共振器（FBARS）具有随着制造变化而变化的谐振频率，但是当在集成电路芯片附近时，它们倾向于匹配。使用分数N合成器确定FBAR谐振频率，并将来自分数N合成器的输出信号的相位/频率与参考值进行比较。该参考可以从低频晶体振荡器，外部信号源或通信信号导出。

摘要： Embodiments provide apparatuses, systems, and methods to convert an analog signal input into a sigma-delta digital output at a high sampling rate and correct for noise components of the digital output. An analog filter coupled to a sigma-delta converter accepts a noise-shaped analog signal from the sigma-delta converter to attenuate signal components of the noise-shaped analog signal at a plurality of folding frequencies associated with a sampling rate of a low-speed Analog-To-Digital (ADC) to produce a filtered output. The low-speed ADC is coupled to an output of the analog filter and samples the filtered output of the analog filter at a sampling rate slower than the high sample rate to output an ADC digital output. Other embodiments may be described and claimed.

摘要： A receiver and a method for controlling power consumption therein are disclosed. The receiver comprises at least one front-end module, an amplifier, an Analog to Digital Converter (ADC) module, a spectrum analyzer and a control module. The at least one front-module is configured to receive and process a RF signal to obtain an IF signal. The amplifier is configured to amplify the IF signal received from the at least one front-end module with a variable gain. The ADC module receives the amplified IF signal and converts into a digital signal. Further, the spectrum analyzer estimates a power level of a signal information and a power level of a noise in the digital signal. Thereafter, the control module controls a variable gain of the amplifier and a variable dynamic range of the ADC based on the power level of the signal information and the noise in the digital signal.
