Hi
I am interested in building one. I have collected many items required like 100msps Analog Devices adc, 133Mhz ram(hoping pc ram might work) and some high frequency opamps, Microchip 32 bit microcontroller and some switches from MAXIM.
I am having trouble designing the front end signal...
drive circuit for back to back mosfet
ok i got it. the voltage across the drain-source (across the mosfet) is applied to gate-source(Vgs). So it like applying 3v and not 12v.
so what is the solution to drive such systems. is it only bootstrapped driver..
what if the load is capacitive (or in...
mosfet gate driver circuits using transistors
I tried low side N channel mosfet circuit and it works perfectly. I dont understand why the high side circuit doesnt work.
high side fet driver circuit
yes that is true. no one explained me that in simple terms.and The problem with wizpic circuit is that the transistors dissipate lot of energy hence it cannot be used.
Actually it is linked to .
i still dont understand why this circuit doesnt work ( high side N...
high side n mosfet driver circuit
I found out the solution. I have tested this and the resistance of the mosfet drops to less than 0.1ohms.
The mosfet acts as a thyristor. To switch ON a mosfet you need to create a isolated secondary supply like using a diode and a capacitor. Remember that this...
solve the heating problem on fet

fet driver circuits
is it the initial current or full saturated current..are you using smps as source..
it can work..but while turning ON and turning OFF the gate voltage will slowly rise and fall compared to the driver circuit..this results in mosfet to be in higher resistance for some...
mos driver circuit
i finally used circuit using cd40106 6 cmos schmitt trigger not gates in parallel.
the cmos IC can work at maximum 15volts. you can shift one not gate to get a non-inverting buffer.
the npn and pnp pair described dissipated a lot of energy because at one point of time both...
4541+mosfet
ok ... are there any commercial switching regulators.i am tired of these mosfets.
i need 3.3v 2a switching regulators.i found lm1501 but it is not available at stores.
are there any famous(like7805) or widely used switching regulators.i was trying mc34063.
mosfet driver circuits
i need resistor values.basically i need a schmitt trigger to drive the mosfet.can it be built using transistors.i am using mc34063 to generate 20v gate voltage.i can use 40XX series cmos buffer.but i want it to be simple and use transistors and diodes.
mosfet driver circuit
i need a mosfet driver circuit made up of transistors like bc547 and bc558. it should be like a schmitt trigger with very low output impedance.
