The circuit was designed to provide protection to the output of power amplifier thereby protecting the loudspeaker from unwanted noise and other elements. Power Amplifier – a type of amplifier built ...

Once an engineer has designed the audio circuit of an amplifier, it would be nice to think that most of their task is complete. However, from a system perspective, that is far from true. At the very ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...
