Abstract
Mevcut bulus, güç yükselticisinin güç çikisi yüzünden olusan yükseltilmis güç çikisindaki faz bozulmasini telafi etmek için bir yöntem ile ilgilidir. Bulus ayrica, faz bozulmasini telafi etme cihazi ile ilgilidir. Cihaz, güç yükselticisinin (40) girisine bagli bir faz-kilitleme ve üst degistirme döngüsü (30-39) içerir. Kisaca, çözüm, yükseltilecek sinyalin bir kisminin (epha), bahsedilen sinyal ile güç yükseltici (40) çikisindan geri beslenen yükseltilmis sinyalin (eout) bir parçasinin birlestiren devreye (35) geri beslenmesini içerir, böylece, birlestirici devreden yeni bir geri besleme sinyali elde etmek için iki sinyal birlestirildiginde bir sinyalin öbür sinyal üzerine olan baskinliklari arasinda düzgün geçisler saglanir.
