Phase Locked Loops (PLL) and Frequency Synthesis
rfic.eecs.berkeley.eduPhase Locked Loops A PLL is a truly mixed-signal circuit, involving the co-design of RF, digital, and analog building blocks. A non-linear negative feedback loop that locks the phase of a VCO to a reference signal. Applications include generating a clean, tunable, and stable reference (LO) frequency, a process referred to as frequency synthesis
