什么是classDamplifier因为在完全导通的时候晶体管的电流很大但是压降很小由其饱和电阻决定而在截止的时候加在晶体管的电压很高但是流过晶体管的电流很小只是其漏电流而已 什么是classDamplifier D类放大器的工作原理 D类放大器是一种完全不同的放大器,其实称之为D类放大器似乎并不恰当。因为它并不只是放大器工作点...
of the class D amplifier from being decreased by providing a bridge circuit and 1st and 2nd conversion circuits that convert a voltage drop across one MOSFET into a current signal representing a voltage across the MOSFET or the like to the class D amplifier to avoid waste of the output power...
