In an NMOS, does current flow from source to drain or vice-versa?
The 'source' means the source of the majority charge carriers of the device. If it is NMOS it would be the source of electrons. If it is PMOS it would be the source of holes. The 'drain' means the …
cmos - NMOS: what exactly forms the inversion layer - Electrical ...
Sep 14, 2014 · The source and drain diffusions (for an nmos) are n diffusions in a p-type substrate. Their junction with the substrate needs to be reverse biased. If it was forward bias, …
Circuit with LTspice default NMOS model does not work as expected
Nov 26, 2018 · The circuit is a voltage source in series with a resistor in series with the NMOS. A pulse voltage source is connected to the gate terminal to turn on/off the NMOS. After I …
nMOS passing 1's poorly and pMOS passing 0's poorly
"nMOS transistors pass 0's well but pass 1's poorly" and "pMOS pass 1's well but 0's poorly". What exactly do these statements mean and why is it so? An enhancement-mode MOSFET …

Nov 26, 2015 · When the NMOS is connected to VDD and turned off, why does it not block the current completely? 0 The role of pull-up resistor to allow inverted logic high/low voltage …
nmos - N-MOSFET Gate to Drain short circuit configuration and …
Oct 17, 2020 · Turning the bottom nmos on will form a voltage divider, getting the output close to zero. This makes this circuit an inverter, although it is not a particularly good one, it is better …
transistors - NMOS: why VGS instead of VG? - Electrical …
I am having lots of trouble trying to understand how the mosfet is triggered. The text I read assumes the source of the NMOS connect to ground, while a positive voltage is applied at the …
