Digital RF Modulation Analysis with Fast Circuit Envelope
應用說明
The Fast Circuit Envelope (FCE) technique uses algebraic equations to describe the relationship between the input(s) and the outputs of a circuit. By determining these equations, one can predict the circuit's response to any input signal without needing a circuit-level simulator like Harmonic Balance or Circuit Envelope solvers. The goal is to bring a simplified yet sufficiently accurate circuit description into a system-level platform.
The Fast Circuit Envelope (FCE) technique aims to abstract the original device's complexity and construct a comprehensive relationship between the input and output signals. Abstracting from the internal topology requires finding the right balance between the generated model's accuracy and complexity. Whether designed on silicon or III/V substrates, RF circuits and devices are subject to physical phenomena that may be important to characterize to represent their behavior accurately.
