Hi,
I am trying to have a nanosecond-rise spike across an inductor as shown in the picture below.
I tried with a mosfet to ground (coil between 6V and mosfet's drain) but I get a lot of ringing before the line stabilises to 6V. That is the case even keeping the traces extremely short and large and using all smd parts (to minimise parasitic inductance) etc.
Any ideas/suggestions? Even a completely different circuit would do. All I care is to recreate that fast rising (nanosecond) pulse.
Thanks
Rico
