How to simulate the input-referred noise voltage of an amp
or LNA in HSPICE? Thnaks a lot!

Re: How to simulate the input-referred noise voltage of an a

Just add a ac sweep and a noise analysis statement. This is an example for hspice:

.include 'opamp.sp'
.global vdd vss
x1 vp vn out opamp
vdd vdd 0 10
vss vss 0 -10
vp vp 0 0 ac 1 0
vn vn 0 0
.op
.option post
.ac dec 10 1 1e+9
.noise v(out) vp 10 $ vp is the refered input
.print noise inoise onoise
$ ...
.end

The inoise is the input-refered noise and is printed into the hspice output file.

Is the same in OrCAD PSpice 9.0 :?:

Useless. Cross-posting. Other post deleted.
Warning!

.noise in cadence
or hspice
you can get it
