Re: plot the output current!
Sorry, Actually I am using Cadence Virtuoso simulator.Normally I plot the gain by selecting output node first then input node in my simulator, that why i said which among three input i should select. Symbolic image of my design is attached...
Re: plot the output current!
Hello sir,
the output current is
Io= (I1 sC2+ gm I2- I3 (s^2 C1 C2 Rx+s C2+ gm ))/(s^2 C1 C2 Rx+sC2+gm ) and depends upon three inputs I1, I2, I3. its output current of current mode universal biquad filter. It implement different filter response for I1, I2, I3 value...
Hello, the output current
Io= (I1 sC2+ gm I2- I3 (s^2 C1 C2 Rx+s C2+ gm ))/(s^2 C1 C2 Rx+sC2+gm )
is depend upon three inputs I1,I2,I3 simultaneously. when I1=I2=I3=I (let 1mA), the ac response implement high pass filter. my problem is that after applying ac simulation how to plot gain vs...
Hello frnds, I am involve in design of current mode analog circuit and working on TSMC0.18um process (cadence). Pls tell me how to find ac current gain, if output current depends upon two or three input signals.
yes i am varying the frequency of ac input current source. pls tell me brief steps to plot current vs frequency at output as well as at input itself in cadence.

Thanks, its working. Is this affect dc operating point or not
Thanks, the current at output terminal with 0Ω resistor plot the curve, but when i want to plot current gain (output current/input current) vs frequency curve it shows a problem, i am applying ac current source at input terminal. Is it possible to plot current vs frequency curve at input...
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

pls...
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.
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...
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.
Hello friends i am working on TSMC 0.18um process and want to design second generation current controlled current conveyor (CCCII). My question is that, what should be the expected gm/Id ratio of different transistor of CCCII(image is attached). pls reply...
