    • In accordance with an embodiment, a radio-frequency (RF) front-end for a radio configured to receive an RF signal at a first frequency includes an antenna port configured to be coupled to an antenna, and a notch filter having an input coupled to the antenna port. The notch filter is configured to reject one or more frequencies, such that the first frequency is a harmonic or intermodulation distortion product of the one or more frequencies. The RF front-end also includes a piezoelectric filter having an input coupled to an output of the notch filter and an output configured to be coupled to an RF amplifier. The piezoelectric filter has a pass band comprising the first frequency.
    • 根据实施例,被配置为以第一频率接收RF信号的无线电的射频(RF)前端包括被配置为耦合到天线的天线端口和陷波滤波器,其具有耦合到 天线端口。 陷波滤波器被配置为拒绝一个或多个频率,使得第一频率是一个或多个频率的谐波或互调失真积。 RF前端还包括压电滤波器,其具有耦合到陷波滤波器的输出的输入和被配置为耦合到RF放大器的输出。 压电滤波器具有包括第一频率的通带。

    • Embodiments of the invention relate to integrated circuits comprising inputs for receiving an input signal and a plurality of clock signals having a predetermined phase relationship. The integrated circuit may include a plurality of track-and-hold devices and a plurality of slicer devices. Signal outputs of two track-and-hold devices may be coupled to signal inputs of one slicer device, one of the two track-and-hold devices and the slicer device being coupled to a first input configured to receive a first clock signal and the other track-and-hold device being coupled to a second input being configured to receive a second clock signal.
    • 本发明的实施例涉及包括用于接收输入信号和具有预定相位关系的多个时钟信号的输入的集成电路。 集成电路可以包括多个跟踪和保持设备以及多个限幅器设备。 两个跟踪和保持设备的信号输出可以耦合到一个限幅器设备的信号输入,两个跟踪和保持设备中的一个和限幅器设备被耦合到被配置为接收第一时钟信号的第一输入端,并且 耦合到第二输入的其它跟踪和保持设备被配置为接收第二时钟信号。
