i know that could be a problem but could this make the output voltage equal to the input voltTell that how with 0.5A input current , you want achieve 3 amperes from that simple circuit ?????!!!!!!!!!

can you attach the circuit that you are using ?
i didn't get it what to reflect on the gs(gate source!) junctionIt is completely wrong!
your driving has , problem . you should reflect 15 volt just across the GS junction.
Good luck
Goldsmith
well ! if you simply , give some volts to the gate at this arrangement , it will be at linear region , and it means that , your mosfet at high currents , will convert to the HELL !!!!!!! ( high value of dissipation ).
so you should follow , this circuit :

gate to source -10.6 vcan you show me the voltage across the gate-source ?
Respect

how to fix this?The circuit with the LM324 doesn't work because the output of the LM324 cannot reach the positive rail so the PMOS can never turn off. It might have worked if the opamp was rail to rail output.

i'am checking the implementation first on a breadboardResold all components near Capacitor and check its Function again.
