1、隆宇准乙类动态同步偏置功放模块的工作原理和特点是什么? 答:用于音频的功率放大器,从效率角度来讲乙类推挽方式为最高,但由于它没有静态偏置电流,不可避免地会产生交越失真,所以人们都给乙类放大器提供一定的静态偏置,用所谓的甲乙类方式来消除失真现象。我们的这种准乙类动态同步偏置功放电路在保持原经典的乙类放大器无静态偏置电流和它的高效率品质的基础上,巧妙地在差分前级的恒流源和供给单端电压驱动级偏置环节中采用模拟动态开关
What is the working principle and characteristics of Longyu Class B Dynamic Synchronous Bias Amplifier Module? A. The power amplifier used for audio is of the highest push-pull type B from the efficiency point of view. However, since it has no static bias current , Will inevitably produce cross-over distortion, so people are to give Class B amplifier some static bias, with the so-called A and B class way to eliminate distortion. Our class B dynamic synchronous bias amplifier circuit to maintain the classic Class B amplifier without static bias current and its high efficiency based on the quality of the pre-differential in the first class of constant current source and supply single-ended Voltage-driven stage bias using analog dynamic switch
