When voltage is below a certain level, the output of the circuit/component must be zero volts.
When the voltage is above a certain level, the output of the circuit/component must be that level.
How can I accomplish this using passive non-mechanical devices?
... where Vcl is your certain level voltage.G_Switch n1 n2 VCVS PWL(1) c1 c2 0V,0V Vcl,V(n1,n2)
You can't do that with just "passive" parts (resistors, capacitors, inductors).Hello,
I would like to do something like a relay does, but using non-mechanical but still devices. The functionality I want is this:
When voltage is below a certain level, the output of the circuit/component must be zero volts.
When the voltage is above a certain level, the output of the circuit/component must be that level.

Place in series voltage barrier composed of zener diodes and a current through this barrier to a resistor will flow only at higher voltages. You can go as low as knee voltage of ordinary diodes.
Yes you are right,I am not willing to guess what you want to do with this gate. Rephrase your first post please.
Do you have actually a problem or you are asking generally about diode-resistor gates?
You can't without adding more active devices.Well, this problem is known to this king of gate, I am trying to build one that eliminates this problem, for hobby.

In other words, you already found out that an amplifier solves the problem.I have done that using an output relay, but the relay IS a "saturated amplifier" (switch) and it's mechanical.

Do you want us to prove why it's not only sufficient but also necessary?
