    Woo-Woo MOSFET switch question

    Aha.. I wonder why then is ground symbol so often used in addition to + and - of a power supply. More so confusing is the fact that the "ground" side is actually the source of electrons. This is cause "convetionional current" (to hell with it) follows the flow of imaginary positive charge, not...

    Woo-Woo MOSFET switch question

    Thank you! Like i suspected but wasn't sure. Now, i want to interupt discharge from a HV cap and i wasn't planning on grounding it. Let's just say device might have to operate where ground connection isn't available. Isn't the - of the cap enough of "ground". Does ground have to be physical...

    Woo-Woo MOSFET switch question

    Ok, i'm getting no responses, so a simpler question that will also help. In the common emmiter BJT amp example below, does the 1V signal source see the 5V battery?

    Woo-Woo MOSFET switch question

    Some simple example of high voltage MOSFET switch circuit would help the most. I tried googling it, nothing really simple and helpful.

    Woo-Woo MOSFET switch question

    Thank you, i know about threshold voltage and how it affects the width of the channel making FET more "ON" etc..that is not what's confusing me, but the biasing. Let's suppose you want to run a high voltage MOSFET as a switch, let's say Vdd is 4kV. Let's say you use common source configuration...

    Woo-Woo MOSFET switch question

    Thank you, i know threshold voltage varies etc. What's confusing me is does the gate have to be brought up to Vdd + those 5V or whatever or. For example if Vdd was 1000V, would the gate then have to be at 1000V + ~5V or? I can not understand this.

    Woo-Woo MOSFET switch question

    Hi, i am just learning how to use MOSFET as a switch. I am watching this video So in the video, Vdd is 9V and Vin is +5V using a separate power source. Now this is confusing me. In BJT base has to be 0.6V above emitter. How does this translate to MOSFET? In other words, if Vdd was not 9V but...
