Title: Psrr specification
Post by ioannis on Apr 12^th, 2007, 3:32am

Hello,

my main target is to verify the output characteristics of an amplifier. For test reasons I picked the OpAMp from Analog Devices OP-420G. In addition I found this howto article: http://www.automotivedesignline.com/howto/securitysafety/194500113?term=macro&x=&y=
Now I’m interesting to simulate the PSRR characteristic as it is show in the article above! I do the simulation with hspice. How do I have to proceed?

Hi,

If you have a SPICE model of analog devices OP-420G, of course you can simulate PSRR using the configuration shown in the article.
