Switchable PLL Frequency Synthesizer andHot Carrier Effects

In this paper, a new strategy of switchable CMOS phase-locked loop frequency synthesizer is proposed to increase its tuning range. The switchable PLL which integrates two phase-locked loops with different tuning frequencies are designed and fabricated in 0.5 μm n-well CMOS process. Cadence/Spectre simulations show that the frequency range of the switchable phased-locked loop is between 320 MHz ...

FH-SS DDS-PLL based Frequency Synthesizer

A scheme of frequency hopping spread spectrum (FHSS) frequency synthesizer suitable for synthesis of radio-frequency (RF) carrier signal in very high frequency (VHF) band is proposed, implemented and tested. The synthesizer is based on the direct digital frequency synthesis (DDFS or DDS) and phase locked loop (PLL) with dynamic monitoring of varicap’s voltage to reduce switching time. The resul...

Simulating and Designing a PLL Frequency Synthesizer for GSM Communications

Phase locked loops (PLL) are used in almost every communication system. Some of the uses include recovering clock from digital data signals, performing frequency, phase modulation and demodulation, recovering the carrier from satellite transmission signals and as a frequency synthesizer. It is very well known that there are many designs in communication that require frequency synthesizers to ge...

Prescaler PLL Frequency Synthesizer with Multi-Programmable Divider

In the phase locked loop (PLL) frequency synthesizer which is used in a higher frequency region, the prescaler method is employed in order to increase the operating frequency of the programmable divider. However, since the fixed divider whose division ratio is same as the prescaler is installed at the following stage of the reference divider, the reference frequency is decreased and the perform...
