Abstract

크로스오버 왜곡을 갖는 바람직한 출력 클립핑 특성을 가져오는 출력진공관들의 그리드에의 전류의 흐름으로 인해 고입력신호레벨에서 오버바이어스된 B급 푸쉬풀 진공관 증폭기에 관한 압축을 에뮬레이션하기 위한 고체 증폭기가 기재되어 있다. 본 발명은 각각이 하나의 입력회로와 하나의 출력회로를 갖는, 적어도 한쌍의 B급 접속 고체소자를 포함한다. 상기 출력회로들은 혼합을 위해 접속된다. 각쌍의 고체소자의 상기 입력회로에서의 바이어싱소자는 각 소자의 상기 입력회로와 상기 출력회로에서 클립핑레벨 옵셋을 확립한다. 상기 입력회로와 상기 출력 회로에서의 클립핑소자는 각 소체소자의 상기 입력회로에서의 옵셋신호를 클립핑하고 상기 출력 회로에서의 옵셋신호를 클립핑한다. 충전소자는 상기 입력신호가 입력 클립핑소자보다 더 클 때마다 상기 입력회로에서의 상기 옵셋을 오버바이어스한다.
상기 오버바이어싱은 진공관증폭기와 연관된 바람직한 압축을 에뮬레이션하기 위한 크로스오버 왜곡을 가져 온다.
