Re: Interesting inductor

I'm hassling with inductors now too, but at the other end of the speed
spectrum.
 We want a programmable inductor, from maybe 1 mH to 500 mH or so,
maybe 100 mA. Sounds like an inductive DAC, a series string of
inductors with shorting relays. If the step inductance ratio were,
say, 1.8:1 we could have some hidden bits, more than the customer
sees, so we could get pretty close to his requested value.
 We could test all 2^n steps, make a list, and select the closest to
his request.
 We're simulating loads to an engine control computer, torque motors
and solenoids and steppers.
