摘要
音频功率放大器是音响设备的重要组成部分,功率放大器各级电路的设计、元器件的选用对功率放大器的性能会产生重要影响。实践证明,通过引入差动放大器、渥尔曼电路(Cascode)、晶体管与场效应管混合电路、多管并联输出电路的设计,采用音响专用元器件,对改善放大器的高频响应、瞬态响应、转换速率、减少瞬态互调失真、提高功率放大器的稳定性和控制力等方面取得明显的效果。
Audio power amplifier is a very important part in audio equipments. The design of the power amplifier and se- lection of components exerts an important effect on the performance of power amplifier. Practice proves that frequency re- sponse, transient response, transient distortion and the stability of power amplifier achieves good results by design of differ- ential amplifiers, Cascode, transistor and FET hybrid circuits, multi - parallel output circuits.
