| 摘要: |
| 本文证明在注入锁定情况下,压控注锁振荡器实质上是压控可变相移振荡器(VCPSO)。分析了由鉴频器(FD)、鉴相器(PD),以及FD加PD同VCPSO构成的三种环路,并分别给出了等效框图,及相应的闭环相位传递函数。为了与一般锁相环路相区别,分别称之为Ⅰ、Ⅱ、Ⅲ类零阶最小剩余相位误差环。 |

| Abstract: |
| This paper will prove that voltage controlled injection-locked oscillator
(VCILO) is voltage controlled phase shift oscillator (VCPSO) in practice. Three
kinds of loops consisting of frequency discriminator (FD), phase detector (PD)
and FD+PD+VCPSO are analyzed and given respectively equivalent block diagrams
and the correspondent closed-loop phase transfer functious in the paper. In order to
differ from usual PLL, they are called as class-A, B, C zero-order minimum resi
dual phase error loops respectively. |
