Executive Summary : | Electronic design automation (EDA) or electronic computer-aided design (ECAD) is a class of software tools based on computer algorithms. ECAD algorithms play an essential role in the modern-day electronic circuit design industry. Digital circuit designers mostly use the EDA technology as compared to analog and RF circuit designers. Most RF and analog circuits are still designed manually, requiring specialist knowledge unique to analog and RF design (such as matching concepts). In the recent paper entitled “Design of Multi-Port With Desired Reference Impedances Using Y-Matrix and Matching Networks”, the author has shown that analog and RF circuit design can also be automated up to some extent. Two automated design algorithms have been proposed for RLC circuit realization of the desired scattering matrix with impedance transforming properties. The scattering matrix describes power transmissions and reflections among the ports of the network. It also provides phase-shifting information of the network. The phase-shifting property of impedance matching networks was uncovered by Sinha and De. A design technique was proposed to design matching networks with the desired phase shift. The method was proposed for two-port matching networks. However, modern-day communication systems demand the use of multiple-input and multiple-output (MIMO) systems. To design the matching networks for the MIMO system, we need to extend the desired phase matching network to a multiport matching network with the user-defined transmission characteristic. In the proposed work, we will develop computer-aided design algorithms for the design process of multiport matching networks with desired transmission characteristics. The port-decomposition method, Y-matrix method and matching network design technique with desired phase shift will be used to develop the algorithms. Also, novel design methods will be explored during the execution of the proposed project. The final product of the proposed project will be a software tool used to design and analyze multiport matching networks. The software can be used for educational, research and industrial purpose. Currently, we are focusing on circuit level (ideal components) design. However, physical level design automation of multiport networks is also possible in future. |
