I've done that but it doesn't works...
I thinks it´s because my function but I don't know... dB20(VF("/vout")/VF("/vref"))
I have always the same negative gain...
Re: LDO Gain
Hi,
I'm doing an LDO and I would like to know the gain. Could you tell me how you do it?
I'm doing dB20(VF("/vout")/VF("/vref")) but I'm not sure if it´s that. It's giving me a negative gain?
Could you help me?
thanks in advance
Hi,

someone could help me?
Thanks in advance.
Hi,
could anyone give me an idea how I do this?
I have a Vin is going from 0V to 3V but to my system works I need him to go to 6V to 9V.
Any sugestions? I need to be linear, 0 correspond to 6; 0,5V to 6,5V ... and 3V to 9V..
He has to be with cmos technology.
I'm a beginner, so I apologise...
My line is like in "Zigzag" but I would like only one simple line like the second image in my first post. Do you have any idea why does this "up's and down's"?
I don't know if I explain very well...
thanks for helping me..

Thanks.
Re: See this CADENCE tutorial, sl. 14 & 15 :
If I do an opamp with a negative feedback, what i have to write on the ouput in cadence?
"value(db20(VF("/Vout")/(VF(“/Vmais”) –VF(“/Vmenos”))))" ?
thanks a lot for helping me because I'm desperate...

Re: See this CADENCE tutorial, sl. 14 & 15 :
In my ampop I don't have "outp" and "outn", I only have one ouput and not 3 like the one in the tutorial... Could you help?
I want to calculate the gain, and th tutorial does: "value(db20(VF(“/outp”) –VF(“/outn”)) 0)" but if I had only one output...
