厂方为其投入了最新的电路和高级材料,从而大幅提升了性能和音质,使其比前一代机型E-650更接近旗舰型号E-800的性能与音质。深入一点看,在E-700的前级放大部分,采用了Accuphase引以为傲的独家平衡AAVA音量控制技术(Accuphase Analog Vari-gain Amplifier)。该电路通过从输入信号中创建大小不同的多个信号,通过切换这些信...
A DIY IRF610 Mosfet Class-A Headphone Amplifier Project using a LM317 regulated constant current source (ccs) load.
The class AB amplifier can be designed by usingMOSFETto generate an output power of 100W to drive the 8 ohms load. This type of power amplifier is designed due to its high efficiency, less harmonic, and Cross-over distortion. The circuit diagram of a class AB amplifier using MOSFET is sho...

首先,D类放大会将原始的模拟信号波形,与比它更高频率的三角波(或锯齿波)进行电压比较(透过电压比较器),如此便可将以振幅高低性表示的信号调变成以脉波宽窄性表示的信号,此即是脉宽调变(Pulse Width Modulation;PWM),之后将PWM信号输出到MOSFET场效晶体管上的闸极,以控制晶体管的导通、关闭,同时也在这个阶段进行...

A full-bridge Class D amplifier, however, requires twice as many MOSFET switches as a half-bridge topology. Some consider this to be a disadvantage, because more switches typically mean more conduction and switching losses. However, this generally is only true with high-output power amplifiers (...
