Re: plot the output current!
How could we help you, if you don't communicate what you were trying, and which results you got?
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 selections.
I1=Iin, I2=I3=0 (Band Pass filter)
I2=Iin, I1=I3=0 (Low " " )
I1=I2=I3=Iin (High " " )
I1=I3=Iin, I2=0 (Band reject filter)
I1=2Iin, I2=0, I3=Iin (All pass filter)
For Band pass and Low pass filter I got the correct frequency response (only one input rest are zero)
But for High pass, All pass and band reject filter, I got wrong frequency response (Here more than one input simultaneously), I am stuck and confused that at which input i must click to find gain response.
