Hello,
I design an inductorless Chua circuit based on the design found in
**broken link removed**
and by replacing the LMC6482AIN opamp by TL081
The circuit works but when I tried to connect the output with comparator (open loop TL0821 opamp or LM311) the output signal was vanished.
I tried to couple the two circuit with coupling capacitor using trial and error for the values. At C=110nF is threshold. below this value the random signal work but no output at the comparator. Above this value the random signal changed to periodic sine wave which is not required.
My question: how can I design coupling capacitor between the two circuit to generate random bits?
Thanks a lot
