    [SOLVED] Get rid of the active zone in transistor

    Photoresistor (which I`m actually using) https://en.wikipedia.org/wiki/Photoresistor Sorry, a typing mistake. I need an ON/OFF operation, thats why I'm trying to get rid of the linear zone of the transistor. Yes, the potentiometer could be used as a divider by grounding it, but not the...

    [SOLVED] Get rid of the active zone in transistor

    Thanks, I got it. Well, that circuit was for me to present the theoretical thing and understand the principle based on your answers. Now this is my actual circuit, it`s a MOSFET, an ifrz44n It's really working, the potentiometer is actually a protoresistor, but I got that linear behavior when...

    [SOLVED] Get rid of the active zone in transistor

    Let`s say that variable resistor is a photoresistor. I need the transistor to get rid of the linear zone (work as a switch) and make the gate to ignore the voltages under the saturation threshold. What do I have to add to this circuit?
