Electret microphone amplifier circuit design using transistors


Posted on Feb 4, 2014

This electret microphone amplifier is designed using common electronic components. This microphone amplifier uses an electret microphone capsule, but can be an dynamic microphone, which have a low resistance. This circuit requires a supply voltage between 5 and 10 volts, is recommended to use a supply voltage of 9 volts DC. Since the circuit has
