چکیده
In this paper a 3.5 GHz down conversion mixer with 20 MHz IF output signal for location-fixed WiMAX systems is presented. The proposed mixer is implemented with TSMC 0.18μm RF CMOS technology with 1.5V supply voltage which utilizes Current-Bleeding and Current-Reuse techniques to improve noise figure and conversion gain of conventional Gilbert-type structure. This mixer achieves 12 dB of conversion gain. For input power less than -36 dBm. The SSB and DSB noise figures are 6.5 dB and 3.5 dB, respectively. The proposed mixer achieved -15 dBm for P1dB and 11dB for IIP3 with power consumption of 10.12 mW. Keywords— Current-bleeding, Current-reuse, Down conversion, CMOS mixers, Conversion gain

This paper works on several methods to get sum of log-normal distribution to calculate CCI. We investigate the details of the the method. Those are applied to determine cell coverage probability for pilot signal in the IS-95 CDMA forward channel analytically. The cell coverage is also simulated by Monte Carlo simulation by computer generated random variable of the co-channel interference. The r...

Noise removal is a vital role in medical imaging, such as in magnetic resonance imaging (MRI). So in order to preserve the important features and to guarantee the correct diagnosis, the authors have proposed a new method for removing noise based on NL-mean filter and diffusion tensor. This paper presents a comparison of the MRI slices images segmentation extracted from a some 3D denoised techni...
