AMPLIFIER DESIGN.

• INTRODUCTION.
  
  
• THE MJR-6 MOSFET POWER AMPLIFIER.
  Using only six transistors this design gives excellent results. A distortion detection circuit is built in, enabling the performance driving a speaker load with music to be checked.
  
  
• THE MJR-7 LOW DISTORTION MOSFET AMPLIFIER.
  With just one more transistor the distortion in this version is reduced to under 0.001% up to 20kHz.
  
  
• AN IMPROVED CLASS-B DESIGN:
  A simple modification to a standard class-B amplifier dramatically reduces crossover distortion and eliminates the need for accurate setting of quiescent current.
  
  
• DESIGNING POWER AMPLIFIERS.
  Information on designing low distortion power amplifiers.
  
  
• AMPLIFIER DISTORTION MEASUREMENT.
  When designing low distortion amplifiers we need a means of testing them, and here an alternative to expensive test equipment is described.
