hello,
I am designing a sample and hold amplifier and don't know how to simulate SNDR. Some guys told me use 'pss' or 'pnoise' in candence. But I also find that there is 'transient noise' in transient simulation option. Is that work if I use the tranient noise and take dft of output voltage? Is there some general way to simulate SNDR?


Thank you for your help!
 

May be this discussion will help you:

The same method can be applied for SNDR = SINAD
 

thanks, i have used the transient noise way to simulate noise performance although it consumes a lot of time.
