# The design, simulation and characterisation of a class-B audio power amplifier | ||
|
||
## Abstract | ||
|
||
In this report I describe the design, simulation and characterisation of a novel, high performance, | ||
medium power (≈ 50 W) class-B audio amplifier. Following a general discussion of amplifier characteristics | ||
and design goals, the amplifier schematic is presented and described in detail. SPICE simulation results verify the design and provide further understanding of circuit behaviour. A brief discussion on the methodologies of good PCB design is followed by | ||
a presentation of the key experimental characteristics of the amplifier along with a comparison to the characteristics | ||
derived by simulation. An amplifier control board which responds to thermal and short-circuit faults and adds radio and alarm | ||
clock features is briefly discussed. The final chapter `recommendations for future work' is a reflection upon the | ||
strengths and weaknesses of the amplifier design and suggest possible means of improvement. | ||
