Research paper thumbnail of A 6–17 GHz linear wide tuning range and low power ring oscillator in 45nm CMOS process for electronic warfare

2012 International Conference on Communication, Information & Computing Technology (ICCICT), 2012

The circuit is simulated in GPDK 45 nm technology in Cadence environment. The simulation result shows wide tuning range from 6 GHz to 17 GHz and the oscillator can be used for electronic warfare application. It has also very low power consumption of about 3 μW. The phase noise of this ring oscillator is found to be -78 dBc/Hz @ 10 MHz offset which can be improved by using more number of stages.

The two stage CMOS VCRO exhibits very low power consumption and wide tuning range when realized using GPDK 45 nm CMOS process. The oscillator has a very wide tuning range from 6 GHz to 17 GHz. Because of its wide tuning range, it can be used for electronic warfare applications. It has also very low power consumption of about 3µW with a supply voltage of 1 V. The phase noise of this ring oscillator is found to be-78 dBC/Hz @10 MHz offset which can be improved by adding more number of stages.

Research paper thumbnail of Energy-Efficient Double Threshold Based Cooperative Spectrum Sensing using Intelligent Soft Decision Approach for Cognitive Radio Networks

Here, we consider the problem of finding optimal pair of transmission power and double threshold difference to improve the energy efficiency as well as to minimize the sensing rounds under the constraints of targeted detection probability and probability of false alarm by applying intelligent soft decision approach such as multiobjective evolutionary algorithms with fuzzy decision making. It is observed that multiobjective hybrid invasive weed optimization and particle sw...
