چکیده
In this paper, Frequency divider by 2 circuit using D-flip-flop is done, based upon this a4/5 prescaler, 16/17 prescaler,32/33 prescalerareverified. Along with it the design of wide band multimodulus 320/321prescaler.CMOS single phase clock pre-scalar,wideband single phase clock 2/3 pre-scaler are also designed. A dynamic logic multiband flexible integer-N divider is designed which uses the wideband 2/3 prescaler, multimodulus,4/5 prescaler, 32/33prescaler. Frequency synthesizer is implemented by using a phase-locked loop (PLL), and it is one of the power-hungry blocks in the RF front-end modules. The firststagein a frequency synthesizeris the frequency divider which consumes a large portion of power The proposed multiband flexible dividerprovides a solution to the low power PLL synthesizers for various wireless communication devices

Design of a Low Power Multiband Clock Distribution Circuit Using Single Phase Clock
The clock distribution network consumes nearly 70% of the total power consumed by the integrated circuit since this is the only signal which has the highest switching activity. Normally for a multiband clock domain network we develop a multiple PLL to cater the need. This project aim for developing a low power true single phase clock(TSPC) multiband network which will supply for the multi clock...

متن کاملDesign and Analysis of Power and Area Efficient 2/3 Prescaler Using E-TSPC Logic
One of the important functional blocks in frequency synthesizers is the high speed dual modulus prescaler. The bottleneck of the dual modulus prescaler design is that it operates at the highest frequencies and consumes more power than any other circuit blocks of the synthesizer. A dual modulus prescaler (also known as divide-by-N/N+1 counter) usually consists of a divide-by-2/3 prescaler unit f...

A dual-modulus (divide-by-16/17) prescaler has been designed using a 0.35μm CMOS technology. It consists of a divide-by-4/5 synchronous divider and a divideby-4 asynchronous divider, all implemented with MOS current mode logic. The operating frequency range is simulated to be from 0.8 to 3.1 GHz including all parasitics. The prescaler including the output buffers driving external 50Ω load draws...
