简介从1994年Pass先生提出一个精简型功放,Zen的设计理念,并发布了第一版电路图以后,直至本文已经过去了8年。在其间,Zen的电路经过设计者与制作者之间的交流和讨论不断得到改进,从Zen1至本文的Zen4分为四个版本。在Zen2中,我们给Zen换了一颗强壮的心,加入了ALEPH电流可变恒流源。ALEPH恒流源的加入,使放大器的输出电流提高了一倍,与Zen1的静态恒流源相比,显著的降低了放大器的失真,提高了输出功率和信噪比。针对Zen电源抑制比低的问题, INTRODUCTION From 1994, Pass introduced a compact amplifier, Zen’s design philosophy, and released the first version of the circuit until after eight years have passed. In the meantime, Zen’s circuitry has been continuously improved through communication and discussion between designers and creators, with four divisions from Zen1 to Zen4 in this article. In Zen2, we changed a strong heart to Zen, joined the ALEPH current variable constant current source. The addition of ALEPH constant current source doubled the output current of the amplifier, which significantly reduced the amplifier distortion and improved the output power and signal-to-noise ratio compared with Zen1’s static constant current source. Zen power supply for the suppression of the problem of low,
