Hello all, I'm trying to design a circuit that would only allow signals above a certain voltage to pass through it, and signals below that voltage to be be blocked.
Specifically, I want to allow a signal of up to 120 VAC (of only about 2 milliamps) to pass through the circuit, while blocking any signal below 15 VAC
That is why I titled this post as "inverse clipping circuit", since its output waveform would be complementary to what a zener's would be.
I want to use the circuit to protect a solid state switch, so as to bypass (but not shunt to ground) any high voltage signal before it gets through it.
I'm almost certain that a zener (or tvs) diode would be involved, but I haven't seen any examples online on how this could be.
Please be patient, my area of expertise is digital electronics, and rarely analog, as in this case.
