Implementation of CMOS Low-power Integer-N Frequency Synthesizer for SOC Design

The paper reports the implementation of a frequency synthesizer for system-on-chip (SOC) design. The epi-digital CMOS process is used to provide SOC solution. This work focuses on low-power consumption to achieve longer life-time of batteries. A 2.4GHz frequency synthesizer has been fabricated in 0.18μm epi-digital CMOS technology for ZigBee applications, which consumed 7.95mW from 1.8V supply....

Implementation of a Programmable High Speed Divider for a 2.4 Ghz Cmos Integer-n Frequency Synthesizer

The implementation of a programmable high speed divider for a CMOS Frequency Synthesizer, using 0.35 μm CMOS technology, is described. The Frequency Synthesizer is part of a RF transceiver to work in the 2.4 GHz ISM (Industrial, Scientific and Medicine) band. The programmable divider employs: a divide-by-32/33 dual-modulus prescaler composed by a divide-by-4/5 synchronous counter, using the Ext...

Designing and Simulating a 2. 4 GHz Integer-N Frequency Synthesizer with 1 MHz Frequency Step

This article consists on the design and the simulation of a 2. 4 GHz Integer-N Frequency Synthesizer with 1 MHz Frequency Step which can be used for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. The effects of the sideband&apo...

Behavioural Modelling and Simulation of PLL Based Integer N Frequency Synthesizer using Simulink

Behavioural modeling and simulation of a PLL based integer n frequency synthesizer has been illustrated in this paper. The synthesizer generates a signal of 5.15-5.25 GHz in the UNII (Unlicensed National Information Infrastructure) lower band which is used by IEEE 802.11(a). All the PLL building blocks are modeled and simulated using Simulink. The PLL performance has been evaluated using MATLAB...
