🔍 Key Concepts

• Decoupling networks and what they do in amplifier circuits • How unwanted feedback between amplifier stages can affect stability • The relationship between power supply variations and oscillations in multistage amplifiers

💭 Think About

• Think about what happens if several amplifier stages share the same supply line without any decoupling components between them • Consider whether decoupling tends to increase or decrease the chance that a small disturbance in one stage will affect other stages • Ask yourself if the purpose of adding decoupling networks is to create oscillations, control oscillations, or to keep the amplifier stages operating independently

✅ Before You Answer

• Clarify in your mind whether decoupling is mainly about isolation and stability, or about generating oscillations • Recall that unintentional coupling between stages through the plate (anode) supply can lead to feedback – is that usually desirable or undesirable in an audio amplifier? • Verify whether well-designed multistage audio amplifiers usually aim for stable, clean amplification or tunable oscillation across stages
