hi AK SAHU,
yes, you should try to solve it but you can try to simulate that circuit using partsim for the graph. I've done some simulation related to that circuit here it is -> "Circuit Partsim Simulation('')":http://www.partsim.com/simulator/#81971
It is not done yet, but you can start from there. You can check the parameters of the circuit setup and try to do some modification. I've found result on my side just try to check on the transient analysis graph.
hope it helps.
Best,
Neil
