I want to use an AC coupling capacitor with a resistor to drive MOSFET at a different voltage to the drive signal. The capacitor and resistor arrangement forms an RC high pass filter.
The equation for an RC high pass filter is Fc = 1/(2*Pi*R*C).
If i want an ideal square wave to pass through the capacitor/filter, what do i set the -3dB point to?
By ideal, i mean an infinitely small rise and fall times, where each level is flat.
I basically want a square wave at a couple of hundred hertz to pass through this as ideally as possible.
Thanks
