Spiral inductors are a key component of mixed-signal and analog integrated circuits (IC's). Such circuits are often fabricated using silicon-based technology, owing to the inherent low-cost and high volume production aspects. However, semiconducting substrate materials such as silicon can have adverse effects on spiral inductor performance due to the lossy...
A new CAD-oriented methodology for the full-wave broadband characterization of coupled microstrip structures for RF/microwave and high-speed digital circuits is presented. The characterization methodology is based on the finite difference time domain (FDTD) technique combined with a systematic extraction procedure using the normal mode approach and multiport network concepts. The...
The focus of this work is on the steady-state analysis of RE circuits using a coupled device and circuit simulator. Efficient coupling algorithms for both the time-domain shooting method and the frequency-domain harmonic balance method have been developed. A modified Newton shooting method considerably improves the efficiency and reliability of...
