Hello,
I designed a circuit in LTSpice and wondered wether or not it would work as I expect it, or if there are any problems with it. I expect the current to be at around 260mA peak. As for the real MOSFET's I would be using: DMG1012 as the n-channel, and the DMG1013 as the p-channel MOSFET. I choose those two because they have a rather low gate capacitance.
Two questions I have right off the bat is:
1.) Could I switch them with a 5V gate voltage ? I'm asking because the datasheet states that the maximum voltage between the gate and the source is +-6V, but then later it says "Gate Threshold Voltage" should be between 0.5V and 1V.
2.) How important is it to match the MOSFET's, and what exactly does it mean to match them ?
