Hello frnds, I am designing a current conveyor circuit, pls tell me how to plot current gain versus frequency curve in Cadence.
 

Without any further information I only can say: Perform an ac analysis and plot the gain as a function of frequency.

actually the input is a current signal and whenever i click input and output node for current gain in ac simulation there is a problem encountered. I am using resistive load at output terminal.

Do you really belief that there is somebody who can help you if you do not describe the problem?
 

Hello, I have attached the image of my circuit. Basic function of second generation current conveyor is that current at terminal "z" follows the current at input terminal "x" (Iz=Ix) i.e gain is unity. Here i am applying the sinusoidal current at "x" terminal, now i want to plot current gain (Iz/Ix) versus frequency plot. How to plot pls help...

Simply inject a current in x (Iac) and display Iz/Ix vs. frequency (ac analysis).
Of course, proper dc biasing is required.

Thanks, I did this thing with resistive load at z terminal but i did not get the plot. It encounter problem to plot the curve when i click on nodes for current gain. it works only when i click for voltage gain at these terminal.
 

Perhaps you want to show the full simulation circuit including current source and probe?
 

You may need to save the currents in ADE first and then plot Iz/Ix using calculator tool. Alternately, you can use an ac current source of 1A magnitude for Ix and just plot Iz, after selecting Iz for saving.

sir I did this but did not work. I applied ac input current source and and taking output with resistive load connected in z terminal (Is it ok). pls tell me detailed steps...

pls show me steps for Iz/Ix vs frequency plot in cadence if possible
