Co-Simulation of ADS and CST for RFIC Performance Verification in Aerospace Communication Systems

Abstract

The increasing application of high-performance communication systems in aerospace activities has spurred the prospect of advanced Radio Frequency Integrated Circuits (RFICs) which are fundamental to successful signal processing in the face of difficult activity environments. Simulation techniques used in the efficient and accurate simulation of RFICs can provide design flaws in the most perfect manner by mimicking what it will feel like under real-life circumstances to come up with the perfect performance in aerospace systems. The proposed co-simulation framework in this paper gives a new design that incorporates the Advanced Design System (ADS), and Computer Simulation Technology (CST) verifying the performance of RFICs in aerospace communication networks. The circuit level design/simulation tool so utilizes ADS (Ansys), and the full wave electromagnetic simulation tool CST (CST Global). The methodology allows a full RFIC selection to be performed that looks at several key components in an RFIC including low noise amplifier (LNA), power amplifier (PA), mixer, and oscillator. A set of case studies are performed to confirm the framework in which it is proven as improving the accuracy of simulation greatly, requiring less time to compute and optimize the performance of the calculation. The outcomes indicate that the single combined ADS-CST model provides a better estimate of RFIC performance resulting in more effective upper-level design of aerospace communication systems. To sum up, the suggested co-simulation environment turns out to be a beneficial tool to speed up the progression of RFIC and raise the dependability of aerospace communication systems.
