web.ece.ucsb.educommunication system. While many applications use a phase locked loop technique to correct for frequency drift, it is good practice to build oscillators with some attempt to minimize such drift by selecting appropriate components. Inductors and capacitors often drift in value with temperature. Permeability of core

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
