To overcome the VCO noise, injection-locked PLLs (IL-PLLs) were proposed to extend the loop bandwidth to O.4f REF but suffered from large spurious tones.
These PLLs exhibit features like small area, large tuning range, and multiple output phases. However, their jitter performance is worse than that in LC- ...
Another way to suppress the in-band noise is by applying noise cancellation PLL (PNC-PLLs) using a delayed-discriminator based phase detector.
