I am attempting to switch an 800mA load at 10Mhz (e.g.with a square
wave). I started with an assortment of BJTs and FETs placing a 10 ohm
carbon resistor load in the collector, (common emitter config). The
squarewave gets pretty sloppy. I added a "speed up" cap to the base
with some improvement however not good enough.
I am lost in a pleathora of differential drivers, totem poles,
cascodes and so forth, but before I proceed I would be interested in
any designs that may already perform this basic task.
Thanks,
Fritz
