It can be deduced from the characteristics of ilpll circuit that injection - locking bandwidth is not only related to the injection - locking bandwidth without feedback loop , but also related to the characteristics of frequency mixing , loop gain and the change of the loop phase . thus , the needed bandwidth can be obtained by adjusting the loop parameters . and the phase noise characteristics are mainly determined by loop transmission factor 由ilpll电路特性的推导得出:注入锁定带宽不仅跟开环时的注锁带宽有关,而且与混频特性、环路增益以及环路相位变化相关联,可以通过调节环路的参数得到所需带宽;相噪特性主要由环路传输因子决定,可以通过调节环路滤波得到比开环注入锁定相噪更优的特性。
