Schmitt Oscillator
I have managed to repair a Copel electric fencer even though the makers would not supply me with a diagram or information on the integrated circuit. I deduced that this is a 40106 hex Schmitt inverter.
I have used previously a simple oscillator as in A in the diagram but Copel used the B version. I have noticed that the B version is used in chips with a built in oscillator. What is the advantage of the extra complication?
A. Frequency = 2.7/(RC)
B The frequency with the components shown is 0.7Hz. Is there a general equation to determine the frequency?
Thank you.
