Hi!
I am trying to switch an LED with an NMOS and I made a simulation for it in TINA. I uploaded a picture about the circuit, to the NMOS gate I put 5Vpp 2.5V offset square wave, and I do not understand why am I having 2.5V on the LED when my square wave is at the LOW state (0V) and only around 4V when it is at HIGH state (5V). Like this the LED is not switched off totally, I want to switch it off when I do not have signal, and switch on when there is. What is the problem? Thanks a lot.
