A 0.1-fref BW 1GHz fractional-N PLL with FIR-embedded phase-interpolator-based noise filtering

This work presents a 1GHz ΔΣ fractional-N PLL based on the noise filtering by FIR-embedded phase interpolator (PI). The proposed PI scheme greatly improves phase linearity by a dual-referenced interpolation and realizes FIR filtering without using multiple CPs, PFDs, and dividers. The designed fract...
