| Abstract: | Among all kinds of microphones,condenser microphone seems to be with the most varies model and type.Variouse internal microphone amplifiers used in varies condenser microphones are introduced,including the simplest ECM microphone amplifier,traditional JFET design(common-drain amplifier and common-source amplifier),vacuum tube microphone amplifier,RF condenser amplifier,etc.The new special JFET design which is neither the traditional common-drain amplifier nor common-source amplifier design is discussed. |
