Hello , In the Vg1 part of the circuit i have a little undesired hunchback.
I dont any positive rise,.
When i added shotkey diode it lowered by half.
Is there a way to eliminate it completly so the signal will go from zero to -12 only?
LTspice files are attached
Thanks.
It's unclear what U2 and its pulsed supply rails are actually meant to do. But as it is now, U2 is what produces a "hunchback" signal (though much sharper than at Vg1). The TL431 and/or schottky can't eliminate it entirely.
Like FvM points out, it's unlikely that the pulsed sources V1 and V2 are realistic. If I slow down the rise time of V1 from 1us to 100us, then the "hunchback" goes away entirely, with no other changes.
