    • The invention discloses an injection synchronization narrowband regenerative phase-locked loop (ISNRPLL) circuit. The circuit includes a synchronous oscillation loop composed by the connecting of an injection synchronization narrowband regenerative voltage-controlled oscillator (ISNRVCO) and an exclusive-OR double frequency circuit; a phase-locked loop composed by the connecting of a digital phase detector, a charge pump and a loop filter, and a D type flip-flop for outputting data. The ISNRVCO does not ask much of the syntonic loop, and can be implemented by integrating inductance on a chip. Preferably, it can be integrated completely by using the deep submicron digital CMOS technology, so there are only a few external elements. Simulation shows that the capture range, capture time and phase noise etc. of the INSRPLL are all better than the conventional phase-locked loop circuit and can be used in GHz level high-speed clock recovery integrated circuit.
    • 本发明公开了一种注射同步窄带再生锁相环(ISNRPLL)电路。 电路包括由注入同步窄带再生压控振荡器(ISNRVCO)和异或双频电路的连接构成的同步振荡回路; 由数字相位检测器,电荷泵和环路滤波器的连接构成的锁相环和用于输出数据的D型触发器。 ISNRVCO不要求很多谐振环路,并且可以通过在芯片上集成电感来实现。 优选地,它可以通过使用深亚微米数字CMOS技术完全整合,因此只有少数外部元件。 仿真表明,INSRPLL的捕获范围,捕获时间和相位噪声等都比传统的锁相环电路更好,可用于GHz级高速时钟恢复集成电路。
