Introduction
With the development of communication technologies and integrated circuits (ICs), the design and application of monolithic microwave integrated circuits (MMIC) and radio frequency integrated circuits (RFIC) become more and more frequent. It is noted that any kinds of RFIC/MMICs are basically constructed by the following components: resistor (R), capacitor (C), inductor (L), transmission line and connector (Tlc), and transistor (Tr). Among them, resistors and capacitors are easily analyzed and designed by simple formulas. Trs are mainly modeled by measurement ways due to their process dependency and not easy scalability. Owing to the complicated parameters and high-frequency analysis of inductor, it is generally analyzed and designed by extracting the closed formula using interpolation, curve fitting, and experience formula. This software adopts the interpolation and iterative method to carry out the synthesis and analysis of the inductor, which is speedy and have good adaptability with the process and structure. Considering the limitations of C/S pattern, this software was based on browser/server (B/S) pattern, and it is applied to inductor, resistance, capacitance, and Tlc.
This paper presents a novel research area involved in fast compute-online and electronic design automation (EDA) realization, so-called COMPOL project or COMPOL software tool online that is applied to designs of RFIC/MMIC passive components. As a design engineer knows, the passive components designs are main time-consuming work among the whole RFIC/MMIC chipset designs, this research work will present an interactive software package that has been fitted and verified by the results based on full-wave full domain Lagrange differential (FDLD) method and experimental approach to realize EDA of RFIC RFIC/MMIC passive components. Its functionality may include analysis, synthesis, optimization, interpolation, and modeling of spiral inductors with any shape on any material substrate for microwave and wireless applications. The developed web platform is based on B/S pattern, by use of VisualStudio.NET and ASP.NET technologies. Through the complete-online processing of the inductors and coplanar waveguide (CPW) designs, it is approvable to expand to design applications of other passive components such as resistor (R), capacitor (C), Tlc, etc. This fast compute-online algorithm makes one case design possible to be done online in the time range of...
