Perfect Compensation Envelope for LRL frontend
 

Real Bode plot. I have called it staircase for the GOLDEN SUN! :)

You should get like this with signal generator sweep via o.scope. All this work perfect with only one uA741. I have no money to buy expensive super-puper OPA! :lol:

The frontend have:
1 Ferrite antenna
3 Important rewsistors
2 Important capacitors and
1 bipolar supply.

Other resistors and caps are for decoupling. Work with several Li-Ion 18650 or 18630 Chinese batteries.


Thats's all
Regards :)
