When I invoke SP parameter file to do tran simulation.Just as the picture shows,parameter is set in this way,and n2port is connected in this way.So,is there any error? any other setting needed?
Thank you:grin:
What is the difference between small signal and large signal in mixer? and in OPamp?
What is the difference between small signal and large signal in mixer? and in OPamp?
Usually, we use small signal to analyse OP amp,the reason for which, I think,is because that the small signal don't exist...
Yes，I am using small signals to set BJT region.But you mean Gilbert cell would be faster when operate it in saturation,right?I don't understand this.could you please explain it in detail?Thank you very much.
In addition,the index I mention is conversion gain,NF,and so on.
I really don't know how to set the DC voltage of Gilbert mixer,especially the BJT.
working region of BJT would make difference to the function or index of mixer?
Thank you very much.
