SNR in Cadence 5.0.33 (Read 2960 times)

fran2k5 Junior Member Offline Posts: 29	SNR in Cadence 5.0.33 Mar 19^th, 2006, 6:27am Hello everybody, I would like to ask you how to calculate from simulations the SNR at the output of a sigma-delta modulator. I am currently using Cadence Spectre 5.0.33. Is there any way with the use of the Calculator? Thank you very much, frank2k5

fran2k5,

� If SINAD is acceptable, then you can use the Spectre's Fourier
analysis tool. Unfortunately, the analogLib implementation is
incomplete and you will need to manually setup the Fourier
analysis.

It only provides the magnitude and phase of harmonics for a specified fundamental frequency. Did I get anything wrong? Thanks, fran2k5
