Re: removing crosstalk spike from a signal question


 

Hello , ?its CB capacitance of Q1 which passes the spike from the nagtive -12V pulse.

When I put a resistor between base and collector the pulse Vg2 gets moved exactly to the spike place(so no more spike issue).

However Q1 is a mechanism where I delay P12 signal by delaying the Vbe of Q1.

now that I add a resistor between base and collector ther is no more delay?

Is there some solution to this problem?

Thanks.?
