thank you sir,First you need to state what is the "proper voltage wave form" you expect, voltage. frequency. and wave-shape.
Otherwise we are guessing.

Sir, I have PINTEK FG - 32 and I am looking for 10kHz to 40kHz frequency rangeYour function generator needs to be able to drive the gate with a high enough voltage (well above Vgs(thr)) to turn on the FET. At high frequencies the gate current required to switch the FET quickly can be large.
There is common connection between supply and function generatorThe circuit assumes that there is no common connection between the function generator and the DC supply not even a mains earth connection. If this assumption is wrong then the circuit won't work.
