Reference Injected Phase-Locked Loops (PLL-RIs)
IEEE Transactions on Circuits and Systems I: Regular Papers, 2017 In this paper, we use synchronization to reduce phase-locked loop (PLL) phase noise and improve its locking behavior with an attenuated reference signal injection (RI) into a voltage-controlled CMOS delay-line ring-type oscillator. The transient and steady-state behavior of the PLL-RI are described by a nonlinear differential equation, which is further

Low-Jitter Clock Multiplication: a Comparioson between PLLs and DLLs [PDF]
, 2002 This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume
