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
Developing and Using Program Logic: A Guide
www.health.nsw.gov.auiv. Identify any feedback loops, i.e. where a higher level outcome affects (or ‘feeds back’ into) a lower level one. This can be important when participation in a program (a lower level outcome) is affected by the success of the program in achieving anticipated impacts and outcomes (higher level outcomes) (e.g. a program that improves the
