TRANSİSTÖRLER
Transistörler pek çok elektronik devrede gerekli bir işlem olan sinyal yükseltme işlemini gerçekleştiren elektronik devre elemanlarıdır. Sinyal yükseltme temel fonksiyonun yanında, transistörler daha başka fonksiyonlara da sahiptirler. Örneğin, anahtarlama elemanı olarak kullanılması gibi...
A – YAPISI VE TİPLERİ
Transistörler de diyotlar gibi P ve N tipi yarı iletkenlerin birleştirilmesinden elde edilirler. Ancak transistörlerde bir değil iki birleşme yüzeyi vardır.
1 – PNP YÜZEY BİRLEŞMELİ TRANSİSTÖRLER
PNP tipi transistörlerde, ,iki adet P maddesi ve arasına ince bir N maddesi yerleştirilmiştir. Aşağıda verilen şekil 1.1 de PNP transistörünün yapısı ve sembolü görülüyor.

bu transistorler işlemcilerin hızlarınında temeli aslında ne kadar cok sığdırabilrlerse işlemcinin içine o kadar hızlı oluyor :)
