how to plot Vin Vs Vout curve in cadence.

[muffassir]

hi alll,

i want to plot the Vin voltage vs Vout curve in cadence ADE L .my circuit is having capacitances at the input ..so i am unable to get it through DC analysis..How can i plot the above curve.

thanks in advance!!!!

hi...
dont know about cadance but in spice it can be plot using command .print

Run a TF analysis, which will give you Vout/Vin. Or a std. AC analysis, then use ADE's calculator to plot Vin/Vout .

Hi Erikl ,
Thanks for ur reply,

Here below is my schematics(in gpdk180nm tech process with both the mos of same size) attached.
Here ip is input pin for inverter.vtun is the input pin for giving the tunneling voltage for the tunneling of electrons through the floating gate.
Capacitors used have the value of 1pF each at the input.




Please refer the below attached test schematics.
The input to the inverter is the Pulse voltage of v1=0 and v2=1.8V .the Total time period=20ns,tr=tf=1ns



I dont know what and which fields to filled by what value in the TF analysis..If u elaborate and help me with the values it will be appreciable.

below is the attched empty form of the TF analysis...the same problem i am getting with the AC analysis...Please help me out.

Currently I have no access to C@dence ADE, sorry. Use the std. help docu!

For ac and xf analyses use Frequency as Sweep Variable, for the Sweep Range use Start-Stop and type in your lower resp. higher frequency limits. The Output should be clear, I think.
