On-chip EM modeling at mm-wave frequencies requires design methods that incorporate the layout and verification macros of IC EDA tools with parameterized EM CAD. We propose a novel, flexible design flow for 3D EM modeling of BEOL structures that allows for parameterized design of BEOL structures using Pcell elements as seed, thereby reducing the time required to generate the full simulation model in EM CAD. The method is illustrated by the co-design of a 94 GHz directional coupler.

Breast cancer detection depends on accuracy of complex permittivity profile reconstruction in breasts. In microwave imaging of breasts, large size matrix is inverted to reconstruct complex permittivity profile of breast models. In this paper, computation time of matrix inversion is reduced by exploiting symmetry present in breast models. Group theory is a powerful tool to exploit symmetry which also provides better results in the presence of noise.

This paper presents an algorithm for the generation of a multisine signal capable of accurately mimicking bandwidth and first order statistics such as the probability density function and the peak-to-average power ratio (PAPR) of an arbitrary digitally modulated signal. The implemented algorithm outperforms state-of-the-art multisine design procedures by proposing a solution capable of achieving an arbitrarily low PAPR error with respect to the digital signal being decomposed. This innovative step enables a fast multisine-based power amplifier characterization with results that closely match that obtained using the actual digital signal.

More and more CMOS integrated circuits operating at terahertz (≥ 0.1 THz) frequencies have been reported recently. However, design environments and techniques are not as well established as for RF CMOS circuits. This paper reviews our recent progress in device characterization and modeling for terahertz CMOS design. Finally, as an application example of terahertz CMOS design, low-power high-speed wireless data transfer at 11 Gb/s and 20 pJ and a 7-pJ/bit ultra-low-power transceiver chipset are presented.

Design and development of a concurrent dual-band filtering Low Noise Amplifier has been presented in this paper. Filtering LNA helps in the miniaturization and reduction in noise figure of the transceiver by eliminating an extra band pass filter (BPF) at the output. A CSIR based BPF structure has been used as output matching network. The dual-band bandpass filtering LNA drains 20-mA of current from a 2.8-V supply voltage. Proposed LNA achieves measured voltage gains of 11.6 and 8.9 dB, reflection coefficients of -25 and -12 dB, and noise figures of 3.96 and 2.85 dB at 2.4 and 5.7 GHz, respectively. Measured characteristics of the designed LNA show reasonable gain at widely separated pass bands in 2.4- and 5.7-GHz WLAN bands with ~ 40 dB of stopband attenuation.

In this paper a Whip monopole antenna covering 30-100MHz is designed. The antenna is first simulated using Electromagnetic Simulation software (CST Microwave Studio™). Then it is validated with the measurement on fabricated antenna. The conventional quarter wavelength monopole antenna is a narrow band antenna with bandwidth of the order of 5 to 10 percent of its centre frequency for VSWR less than 2.5, while most of the applications in modern communication and Electronic Warfare (EW) system require wideband antennas. In order to increase the bandwidth of monopole antenna, a matching network is incorporated. The matching network is designed and optimized using Genetic Algorithm (GA) which is a global search technique used in computing to find true or approximate solutions to optimization and search problems. The antenna finds use for Trans-receive application in communication systems, EW and spectrum monitoring systems.

A technique for combined design of the Wilkinson and the Gysel power divider is presented. Close-form design equations are obtained by analysis of the proposed structure. It is shown through a careful simulation study that at one hand a good bandwidth compared to the Gysel is obtained for the proposed combined structure, at other hand a higher power handling capability is also achieved while utilizing only one grounded resistor. A design methodology and comparison with state-of-the art are also included.

A novel approach to analyze the bone mineral density (BMD) based on microwave reflectivity analysis is presented in this paper. The proposed method enables us to overcome the health risks associated with diagnostic techniques such as X-rays for repeated study of the rate of mineralization in the case of fractures or de-mineralization in the case of osteoporosis. In this paper, we demonstrate the application of Microwaves for continuous observation of skull healing process during post-cranial surgery period. The proposed technique can be a potential clinical model in future for extracting target characteristics such as bone deposition thickness and other cranial defects. Based on the conclusions of wideband measured data, we propose to design the Transceiver using ultra wideband (UWB) pulsed technology.

SiGe HBT technology transistor provides performance comparable with III-V technologies along with the processing maturity and integration levels commonly associated with Si technology. The present work utilizes 130nm SiGe HBT transistors to investigate the performance of low noise amplifier (LNA) for 40GHz and 60GHz wireless personal area networks (WPANs). The transfer gain S2i was found >9dB with 3-dB bandwidth (BW)>5GHz in the bands of interest. Excellent simultaneous matching at input (S11≤-20dB) and output (S22≤-10dB) with noise figure (NF)<;2.5dB at both the bands were obtained. Theoretically, predicted S-parameters of the LNA were found closely matched with corresponding simulated results. The input third-order intercept (IIP3) was found > 3.0dBm in the bands of interest. The graph of performance ratio (R=S21/PDC) versus noise factor F gives significant advantage for SiGe HBT LNA (i.e. achieve high R at low F) as compared to GaAs HBT and Si CMOS technologies. A new figure-of-merit (FoM) involving S2i, noise factor F, IIP3 and power consumption PDC was found to be significantly higher for SiGe LNA than a previously published experimental result for silicon CMOS LNA.
