Hi -
We are learning noise analysis in my communications circuits class right
now. My instructor does simulations with WinSpice, but I try using
ngspice to do them as well. Up until now it's worked great, but noise
analysis does not. When I try to run a netlist that includes noise
analysis parameters in WinSpice it works fine, but in ngspice I get
errors, telling me "Noise input source Vac not found in circuit" and
then aborts the noise simulation. I have attached my netlist here for
observation; what do I need to change? Thanks.
