[ 1 ] - Improving 3-D Imaging Breast Cancer Diagnosis Systems Using a New Method for Placement of Near-Infrared Sources and Detectors
The objective of this research was to improve 3-D imaging system by near-infrared light emission in breast tissue to achieve a more accurate diagnosis of tumor. The results of repeated experiments in this research have shown that with this imaging system, a more accurate diagnosis of abnormal area depends on the location of the sources and detectors. Therefore, an optimal location model has bee...
[ 2 ] - A 28-36 GHz Optimized CMOS Distributed Doherty Power Amplifier with A New Wideband Power Divider Structure
Background and Objectives: In this paper, a new design strategy was proposed in order to enhance bandwidth and efficiency of power amplifier. Methods: To realize the introduced design strategy, a power amplifier was designed using TSMC CMOS 0.18um technology for operating in the Ka band, i.e. the frequency range of 26.5-40GHz. To design the power amplifier, first a power divider (PD) with a ver...
