Noise in 4G communication systems is a pressing current problem. There are various ways to reduce phase noise. The sigma-delta passive adder entrenched (PAE) approach was chosen for the WCDMA system because it provides spurious level, noise, and low stabilization time. Therefore, applications, this study proposes frequency synthesizer. It then suggested that addition of before modulator's quant...

A fully integrated frequency synthesizer that generates multiple frequencies for use in frequency channelized receivers is designed in 0.25μm CMOS technology. Many of the unique features of this receiver have been exploited to design a highly integrated and power efficient multi-output frequency synthesizer including the poly-phase filters. The synthesizer generates 4, 5, 6, and 7 GHz signals w...
