Has anybody found a vco like LM566 model?

HI,

Has anybody found a vco like LM566 model? I need simulate the running of vco for my students.

thank you so much.

We recommend to look for a specific model at the part manufacturer.

I'm assuming the building block VCO's are unsuitable for your purposes?

For examples, VOLTAGE_CONTROLLED_SINE_WAVE, VOLTAGE_CONTROLLED_SQUARE_WAVE,  or VOLTAGE_CONTROLLED_TRIANGLE_WAVE are building blocks.

It all depends on what you're trying to do.  For example, I was trying to simulate a PLL, but the PLL tool is inadequate.  Hence, I can use building blocks and simulate one that acts like the PLL I'm trying to simulate.

I'm always interested in helping students (and their instructors).  On that note, I just passed along a phase-locked loop circuit to the forum, through a thread I began many months ago. 

This url,

should get you to the thread.

It isn't what I'd call a "designed" PLL, as I tweaked it into operation (the 1k was increased to 10k).  But I think it's still pretty cool to play with, and I thought your students and the others here might like it.  However, do note that I used a building block VCO. ...at least for the moment that is. 😉

I have tries (attached file) frequency is changing but the problem is that its amplitudeis also is changing

I have tried a oscillator controlled by input voltage (attached here), but along with its freq the amplitude is also changing dr_parjit@hotmail.com
