transistors

Transistor

Transistors are used to switch signals(on/off) or amplify signals.

In digital circuits the switching behavior converts raw electrical signals into meaningful decisions

Transistor examples

Unlocking a phone with a fingerprint -

Auto adjusting a screen in bright light -

Transistors evaluate inputs and deliver the correct response

General transistor notes

With no moving parts, transistors switch on and off millions or billions of times per second

Being incredibly small, billions of them can be packed on to a single chip

Power of transistors

Putting transistors into perspective - they are the brains of any modern device, that come from semiconductors.

Semiconductors are the material → transistors are the components made from that material

Transistor responses

A transistor regulates electrical current by responding to a small voltage signal

Signal→Transistor(switches on)→current passes through the circuit

Signal’s absent→Transistor(switches off)→current stops flowing through the circuit
