Frequency and Transfer Function Modeling

Frequency modeling and noise analysis are very important when describing analog and mixed-signal systems. The ability to specify transfer functions in the frequency domain is also quite useful in modeling systems. In this chapter we look at the mechanisms provided by VHDL-AMS for modeling spectral and noise sources as well as for transfer functions in the frequency domain.

13.1 Frequency-Based Modeling

Although the discussions thus far in this book have focused on time-based modeling and simulation with VHDL-AMS, we can also represent frequency domain concepts in VHDL-AMS. In this chapter, we focus on modeling frequency-based views of a system and the interaction between time-based ...
