Various sources of distortion in class A junction transistor amplifier stages are investigated using a unified method of analysis. Expressions for simultaneous cancellation of second and third harmonic distortions at low frequencies are derived giving the design relations between the source and load resistances together with the transistor operating parameters. High frequency effects are considered and a simple compensating method is devised to extend the gain‐bandwidth product to the order of (1/2°C TC r b′b ).
