Linear and Class D amplifiers in the next sec-tion. The block diagram of a linear amplifier is shown below in fig 1. In a linear amplifier the signals always remain in the analog domain, and the output transistors act as linear regula-tors to modulate the output voltage. This results in a voltage drop across the output devices, which reduces efficiency.
