正切锁相环,不仅拖延现象少,而且捕捉时间短。我们的工作着重放在模拟除法器的设计上,数学推导和初步实验都证明了正切锁相环具有一般锁相环的普遍性。一、正切锁相环的环路分析1.正切锁相环方框图图1表示正切锁相环方框图 Tangent phase-locked loop, not only delay less, and capture time is short. Our work focuses on the design of the analog divider. Mathematical derivation and preliminary experiments have proved the generality of the normal phase-locked loop with a tangent phase-locked loop. First, the positive phase-locked loop loop analysis 1. Tangent phase-locked loop block diagram Figure 1 shows the tangent phase-locked loop block diagram
