firstly its beatiful design expample dear author i have little doubt that is 1>Q1 begins to conduct current for input voltages greater than about 3V, and is fully enhanced at 4.5V ###i felt this is wrong as gate is floating MOSFET Q1can not conduct till VOLTAGE ACROSS DIODE D1 REACHES 15 v ( OR input crosses 15 V) , please correct me if i am wrong.
