I'm building a circuit using both depletion and enhancement mode Mosfets.
When power is off, the depletion mode Mosfet is conducting (of course and the enhancement mode one is off.
The state of each toggles when power is applied.
Problem is, I need about 30-50 mSec time delay between changeover states. i.e. there must be a period of time during each transition where both types are "off"
1. Power Off, Depl Mosfet On, Enh Mosfet Off
2. Power On, Depl Mosfet Off, (time delay), Enh Mosfet On
3. Power Off, Enh Mosfet Off, (time delay), Depl Mosfet On.
I'm trying to emulate an electromechanical relay where it is specified that NC and NO contacts can never be closed at the same time.
