The signal integration is made from R8 C9 and C14 R22. Via resistor R18 the capacitor C8 is charged to the difference between the voltage on C9 and the input voltage of the non-inverting input. This occurs for a time that signals a signal. C16 and R31 work the same way.

Yes, thanks very much for that. But please tell us why did you choose such an exotic integrator? Couldn't this have been done with regular low pass integrator topology. Is there any special reason for choosing a bandpass dual feedback integrator? Especially since you are first one to use such in a PI circuit(the ones I have seen). Or did you just pull it out of a hat.Originally posted by scs View Post
If I want to know how an integrator works, I can got to wikipedia.
I want to know the design choices you made and why.Comment

Many people wonder why the integrator is different from all other circuits. This is new and I assure you that it works great. It is not good for 30 years to look at the same schemes.Comment

On the right, there is Bulgarian flag, Is that you, Sacho?

Thanks for being a good sport. because of you, I have good impression of Bulgarian people, you are asset to your country.

BTW... for this afternoon i plan to commit suicide... all because i can't achieve nice pcb design yet!
Sasho's pcb is alright, but it is double sided. I can't do it at home as diy.
So i am trying to draw single sided, probably larger in dimensions.
I did 4 so far, none of those good.
So... today i am making 5th attempt.
...
No wonder... i am quite out of shape and form, haven't done anything similar for quite a while.
Drawing and routing is like sport; more you exercise: better the outcome.
Plan is;
1) draw pcb of original circuit. (to get things even worse; i am stuck only with 100x70mm piece of vitroplast at home, so... thight!)
2) Make it work. Experiment with it. Examine all it's features. Form an impression.
3) Slowly to port it to Atmega platform. Step by step.
4) End up with "digital Disc&GEB" PI. Small pcb, small enclosure. etc.
....
Will see.
Headache is constant.
...
On the other hand, set of complete material for 10 megnetometers is waiting to be done. Also 10 ECHO effects.
All of the sudden i am overwhelmed with too much to do.
Speaking on EHO effects; there is one PT and one TL071 inside. So i ordered 10 pcs each.
Can you believe; NONE of those TL071 are working by specs!???
At first i had doubts on many other things. Than tracing step by step i end up only to suspect on TL071.
So i put DIL 8 socket on one pcb, place one old TL071 from a scrap; and it is working like a charm!
Than i replaced one by one of those 10 new TL's; NONE of those is working at all!???
Fake? Failure? Whose gonna know?
But most certainly we are living in the end of time; since even so cheap and trivial component can be faked or relabeled!

Bulgarians are not jungle dwellers. They are one of the ancient peoples of Europe. John Atanasov created the computer and is of Bulgarian originComment

20 megaohms are made with two resistors of 10 megaohms. There is no problem with the operational amplifiers 062 because the DC gain is 1.Comment
