phase-adjusting circuit
解釋
相位調整電路-
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電路特性的推導得出:注入鎖定帶寬不僅跟開環時的注鎖帶寬有關，而且與混頻特性、環路增益以及環路相位變化相關聯，可以通過調節環路的參數得到所需帶寬;相噪特性主要由環路傳輸因子決定，可以通過調節環路濾波得到比開環注入鎖定相噪更優的特性。 -
