摘要: 注入锁相分频器可在较低输入信噪比下工作,这是其他分频电路不能比拟的优点。本文对注入锁相分频器作了以下工作:(1)给出了输入信号含附加噪声时注入锁相分频器的通用相位方程和等效模型;(2)研究了无噪声条件下调相信号通过注锁分频器的特性及分频器的同步带宽;(3)讨论了输入附加噪声对注锁分频器特性的影响。注锁放大器是本文中n=1的特例,本文的结果也适用于注入锁相放大器。Abstract: An injection-locked divider (ILD) can provide good synchronization at lower input signal to noise ratio, which is its advantage over other types of divider. The general expression of phase equation and equivalent model are presented for the ILD with an input additive noise. In the absence of noise the performance of the phase-modulated signal through the ILD and synchronous ranges of the ILD are given. The effects of the additive noise on the ILD are discussed. The injuction-locked amplifier (ILA) is only a particular case in which n=1, therefore the given results are applicable to the ILA.
