injection locking;ring oscillator;phase-locked-loop;clock recovery 1. Introduction The exponential data growth rates needed for the development of applications such as 5G, IoT, space, etc., led to the research of a new architecture for digital communications called the High-Speed Serial Link (HSS...
Section 2 analyzes the maximum locking bandwidth, locking condition, and phase noise of the locked oscillator under multi-signal injection. In Section 3, the phase behavior in the cascaded injection-locked oscillator array with weak reverse coupling is examined. Based on these analyses, an injection...

This paper presents an injection locked digitally controlled ring oscillator (IL-DCRO). To reduce jitter variations, minimize oscillator spurious signals, and eliminate periodical phase error, a double edge-injection (window injection) scheme with synchronized edge directions is proposed. A combinational...
