Questions tagged [nmos]
A n-channel metal-oxide semiconductor (nMOS) transistor has n-type carriers in the channel. A positive voltage on the gate turns inverts the substrate (PWell) creating the channel and turning the device on. The term may also be used to describe logic circuits built around nMOS transistors.

How to make a PMOS work as a constant current source?
I have a circuit in which, the PMOS is biased to a voltage source, the gate voltage, V1, of the NMOS below varies based on the functioning of the analog circuitry before. Because of this, the current ...

Electric-lock control via NMOS matrix
Currently I am working on the design that allows to control 8x8 electric lock matrix via PIC16F877A.
As in comments for somebody it was not obvious (btw it was mentioned) I am using 64 electric locks ...

NMOS as a low side switch
I am trying to use an NMOS(2N7000BU) to "turn off" the LM350 voltage regulator. I have an OR gate going into the gate of the mosfet, so either input will turn it off. The hope was to ground ...

Can we use NMOS to drive WS2812
My ESP32 control circuits all use NMOS for external control. I wonder if the data control of WS2812 can be driven via NMOS?

What does a thick MOSFET symbol mean?
I have come across a bag of about 5,000 n-type MOSFETs (2n7000), and I figured the best thing to do with them is to build a 6502.
I found a diagram of the nMOS 6502 layout
But I am confused as to ...

Mosfet Linear Region LTspice simulation
I have a question regarding a mosfet simulation I am trying to perform.
Here is the circuit in question.
We can see that Vd=1kV , Vs=0V and Vg=10V(it is a pulsed source)
Now to my understanding I ...

the inverter switching point
As we know the mobility of the "nmos" device is 3x greater than "pmos", and when we want to correct the switching point of an inverter for vdd/2 we usually change the W of the &...

N-channel MOSFET fails as an inrush controller
We have designed a inrush controller using the LTM9100 controller.
The LTM9100 basically controls the ramp rate of the gate voltage, which in-turn controls the raise time of the DC bus across the load....

MOSFET not saturating when Vds > Vgs - Vth
According to Wikipedia, the drain current (\$I_d\$) should stay relatively constant when \$V_{ds} > V_{gs} - V_{th}\$:

NMOS current is negative for a very short time when turning off
I am designing a circuit that uses the 2n7000 NMOS as a switch, controlled by a digital I/O pin from an Arduino Micro.
I made a simulation in LTspice, and I notice that when the NMOS is turning off ...

LTspice Half bridge current spikes
I simulated a half bridge with two NMOS and at every switching event a current spike up to 1.2 A in the voltage source V4 occurs. I used a resistor as load because with any inductive or capacitive ...
