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...

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 ...

Pll Based Frequency Synthesizer Implemented with an Active Inductor Oscillator

High costs, bulkiness, and larger power consumption makes transceiver integration and miniaturization a desired option to discretely implemented transceivers. Furthermore, a frequency synthesizer forms an important part of high-frequency transceivers. In this paper, the design of a fully-integrated dual loop frequency synthesizer is detailed. Previously, frequency synthesizers have already been...

Design and Simulation of Programmable Divider Circuit For PLL Based Frequency Synthesizer

In this paper, the divider circuit for PLL based Frequency Synthesizer has been designed. In the divider circuit, three types of counters have been used namely Prescaler, Main Counter and Swallow Counter. The Divider circuit is a two modulus Divider and it can be used to divide by any value in the range 4635 to 4650 as per the requirement. It uses a two modulus Prescaler and it has two modes of...
