on video how to make inverter with one transistor

 

In this circuit, we will build an inverter with a transistor.

An inverter is a component or device that inverts the state or logic level of a signal to the opposite logic level.

Thus, if a LOW signal is fed into an inverter, it flips it to a HIGH signal.

If a HIGH signal is fed into an inverter, it flips it to a LOW signal.

So an inverter changes the logic state to the opposite logic of what is fed into it.

There are many ways of creating inverters, including with any type of logic chip. You can create an inverter with AND gates, NAND gates, OR gates, NOR gates, and pretty much all the gates by combining them in the correct fashion to produce an inverter. You can create an inverter directly wtih an inverter chip. These are composed of inverter or NOT gates. Or you can create an inverter with a transistor.

In this circuit, we will create an inverter with a transistor.

We will show exactly how this works in detail below.

Components

2N700 MOSFET transistor

1MΩ resistor

jumper wire

The 2N7000 is an N-channel MOSFET.

It has 3 leads, the the source, the gate and the drain.

The input signal attaches to the gate of the transistor. This is the input signal that we want the transistor to invert.

We place a 1MΩ resistor on the drain terminal. The drain also must get a positive voltage. The 2N7000 MOSFET can handle up to 60V at the drain terminal. To this drain terminal, underneath the resistor, we place an output jumper wire. This jumper wire will carry the inverted output voltage signal.

We connect the source terminal directly to ground. -
