A PVT Variation-Robust All-Digital Injection-Locked Clock Multiplier With Real-Time Offset Tracking Using Time-Division Dual Calibration

Although an injection-locked oscillator (ILO) can offer excellent jitter performance on average, its intense phase modification at a given injection rate inevitably degrades spur performance, unless injection timing is carefully controlled. This work investigates a behavioral model of the ILO with d...
