You just duplicate the complete circuit for the other two transistors.
For a 0.2ms period signal, C1 has to provide the current the transistor base through R1, so the C1R1 time-constant should be at least 10 times that period or 2ms.
This gives a C1 value of of 2ms / 5k = 400nF.
I would use at least 1µF.
No,Hi sir, is this correct?
No.is this correct?
Hmm if use a second IC, would the timing be synchronised properly because it is not from 1 ic? Can you modify my LT Spice file attached for better understanding? Thanks, sirNo,
You need a second IC. IR2184.
