摘要
采用电流模技术对高保真声频功率放大进行了研究与设计,结合实验和样机制作,实现了超宽频带超高速功率放大。随着SACD的日益普及,同目前流行的电压模高保真功放的性能相比,电流模高保真声频功率放大器将会有美好的发展前景。
Adopting the current mode circuit, the author makes some research and design of high-fidelity audio power amplifier. In the process of experiment and manufacture of the prototype, audio power amplifier with ultra wide frequency range and ultra high speed is achieved, As the SACD is increasingly popularized, the current mode power amplifier, compared with the prevalent voltage mode Hi-Fi power amplifier, will have a quick development and bright look in the future.
