I have homework to do LM13600 Voltage controlled low pass filter. I draw circuit in microcap and i think i have it correct. But in simulation i have strange data. Can you help me? I up circuit and image with simulation.

 

Hello,

Can you post your schematic as a .png or .jpg file?
I can not read the .cir file.

Here is the low-pass filter schematic from the datasheet:

Yep here is it...
I do this circuit according your schematic that you post.

 

Hello,

That is odd. Your schematic shows a chip with 12 pins.
The LM13600 has 16 pins.



Are you sure you are using the correct chip.

Bertus

 

Yes its correct, because you are using on low pass only one half of chip. Its a second chip on the picture..

 

Hello,

You have the bias on pin 5 in stead of pin 1.
