SpectreRF User Guide
Jan 06^th, 2005, 5:23am

While reading certain parts of the 'Affirma RF Simulator (SpectreRF) User Guide', I can't help start doubting its contents.

Take for example the part 'Noise Calculations Using Pnoise' of chapter 6: 'Simulating Low-Noise Amplifiers'. Isn't using PSS+Pnoise, without applying any time varying signals to the circuit, nothing more than a - rather inefficient - form of plain Noise analysis?

Feedback is much appreciated!

Thanks, Paul

However, it is true that running PSS & PNoise when there is to time-varying signals in the circuit provides nothing over a conventional noise analysis, and runs much more slowly. -Ken
