    Can I combine 2 Laptop power supplies (65W-19V) to provide 90W - 19V for PC?

    Re: Laptop Power Supply I wouldn't recommend connecting them together, any difference in voltage is a dead short between the two supplies, and could cause damage to any regulators, etc... as well as possibly draining a lot of extra current. It probably wouldn't hurt to try it with one 65W...

    hi which is better nmos or pmos or cmos

    In modern integrated circuits cmos is usually used because a mosfet is much smaller than a resistor. Also, with either nmos or pmos there is always leakage current, which is avoided with cmos because only one transistor is conducting. If you're talking about discrete components, nmos transistors...
