MOSFET fall time too slow - Electrical Engineering - Stack Exchange

I've got a 2N7000 connected up to an AVR via a 1k resistor on a breadboard. The top trace shows the AVR pin output, clocking at a couple of kHz.

TALKING ELECTRONICS LED Torch

White LEDs have different "characteristic voltages." A 1,000mcd white LED used in this project had a characteristic voltage of 3.5v and a 3,000mcd white LED had a characteristic voltage of 3.2v.

We have even provided a simple way to produce your own speaker transformer by winding turns on a piece of ferrite rod.

Copyright (C) 2010 by Michal Zalewski There are quite a few primers on electronics on the Internet; sadly, almost all of the top hits resort to gross oversimplifications (e.g., hydraulic analogies ), or convenient omission, when covering subtle but incredibly important topics such as the real-world behavior of semiconductors.

This is a simple square wave oscillator using a 555 timer chip . A timing interval starts when the trigger input ("tr") goes lower than 1/3 V in , or 3.33V.

Schmitt trigger provides toggle function - 2011-03-17 10:00:00 | EDN

http://www.edn.com/article/517408-Schmitt_trigger_provides_toggle_function.php

D-type flip-flops, with the inverted output connected to the D input, can toggle a clock signal. If your circuit has an extra Schmitt-trigger inverter gate, you can use it to accomplish the same thing. Every time you press and release the momentary pushbutton switch in Figure 1 , the circuit reverses to the opposite of what it was before you pressed it.
