Simple Microphone (MIC) Amplifier Circuits using Transistors

The first one is a single transistor simple microphone circuit, very simple to hook up using an electret microphone or MIC and an audio amplifier. Typically the 10K resistor within the microphone’s positive port offers this specific vital voltage for the procedure. The capacitor of 100nF on that particular network prevents the DC component of […]
