Can someone please point me to a circuit that is the same as the image below?
"the same" in what way?
Same chip - only you know that.
Same size - only you know the size of the board.
Same 9 V input - is that from a 9 V battery, an external control signal, or something else - only you know.
Same input frequency - we don't know what that is.
Same output - we don't know the characteristics of the "coil."
"What model chip is best to use that is commonly available?"
No clue. What model chip is on the board you have now?
