چکیده
V m f 4 AbstractA phase-locked loop (PLL) frequency synthesizer architecture for multiple-band applications is presented. A dynamically-controlled switched tuning voltage-controlled oscillator (VCO) is used to achieve superior frequency range and phase noise performance over a conventional PLL. . Implemented in 1 .w CMOS, the PLL has a 111-29OMHz range, phase noise of -92.3dBdHz at a 5OkHz offset, and dissipates 9mW from a 2.W supply.

متن کاملDesign Technique of Phase-Locked Loop Frequency Synthesizer in CMOS Technology: A Review
This paper deals with different approaches to design Phase Locked Loop (PLL) frequency synthesizer. PLL system responds to both frequency and phase of the input signals, automatically raising or lowering the frequency of controlled oscillator until it is matched to the reference in both frequency and phase. The performance of PLL frequency synthesizer is improved by using different Voltage cont...
