Speaking of PWM, I'm looking for tips on making 
a pulse width modulated ultrasonic pulse train.
Like you would have at the beginning of one of
those ill-fated PWM audio power amps.
It's to drive a phaser, actually. No matched fets for me! :-)

Any experiences? Or tips? Ideal would be the Maxim MAX038 but 
not at $30 thanks!!!
