i 've make a circuit according with this links **broken link removed**.
my schematic is
1.but i have not R6=3M on hand ,so empty it. It is prefer 3.8 volt at the output of OP07 pin 6,with the input signal changed,so, i don't know it is cause of the R6 missing?
2.If i settle c1, it is vibrate the lm567's pin 3 ,so i can only short c1,i have no ideas.
