Amplifikatörlerde Çalışma Sınıfları

AMPLİFİKATÖRLERDE ÇALIŞMA SINIFLARI

Bu yazımızda amplifikatörlerin çalışma sınıflarını kısaca inceleyeceğiz. Bir amplifikatörde giriş sinyalinin her parçasının amplifikatörden bir çıkışı olduğunu önceden kabul edeceğiz. Ancak bu her amplifikatör için daima böyle değildir. Bir transistörün uygulanan işaretin sadece bir bölümü için geçirgen olması istenebilir. Bir çıkış işareti üretebilen giriş işaretinin seviyesi bir amplifikatörün çalışma sınıfını gösterir. Buna göre amplifikatörlerde 4 sınıf çalışma vardır: A sınıfı, AB sınıfı, B sınıfı ve C sınıfı.

A Sınıfı Amplifikatörün Çalışması

A sınıfı çalışmada dc çalışma noktası cut-off (kesim) ile saturasyon (doyum) arasında kalır ve kolektör akımı giriş işaretinin 360 derecelik komple saykılında bile akmaya devam eder. Böylece giriş işaretinin aynısı çıkışta da görülür. A sınıfı amplifikatörler, yüksek sadakatleri nedeniyle ses ve RF amplifikatörü olarak radyo, radar ve ses sistemlerinde geniş miktarda kullanılmaktadırlar.

[Şekil 2-15: A sınıfı bir amplifikatörün çalışması]

A sınıfı bir amplifikatörün çalışması

Giriş mevcut olduğu sürece çıkış devam eder (180 derece faz farkı ile).

AB Sınıfı Amplifikatörün Çalışması

AB sınıfı çalışacak amplifikatörler giriş sinyalinin bir alternansında kolektör akımı sıfır olacak (zero current) şekilde bayezlenmişlerdir. Kolektör akımı 180 derece boyunca akar, biraz da 360 derecede akar. Genellikle Push-Pull çalıştırılarak B sınıfının yan etkisi olan "crossover distorsiyonunu" yok etmek için kullanılırlar.

B Sınıfı Amplifikatörün Çalışması

Giriş sinyalinin yarım alternansında kolektör akımı cut-off olan amplifikatörlerdir. DC çalışma voltajı giriş işaretinin olmadığı durumlarda beyz akımını sıfır değerde tutacak şekilde ayarlanır. Kolektör akımı giriş işaretinin sadece ilk 180 derecedeki yarım saykılı boyunca akar.

C Sınıfı Amplifikatörün Çalışması

C sınıfı çalışmada, kolektör akımı giriş işaretinin yarım saykılının çok az bir bölümünde akar. DC çalışma noktası cut-off’un çok altında tutulur. Bu sınıftaki amplifikatörler vericilerde RF amplifikatörü olarak çok yüksek verimlilikle kullanılırlar.

Sadakat (Fidelity) ve Kifayet (Efficiency)

A Sınıfı: Yüksek sadakat (girişin aynısı), düşük verim.
AB Sınıfı: Orta seviye sadakat ve verim.
B ve C Sınıfı: Düşük sadakat, ancak yüksek verim (kifayet).
