Abstract
In an amplifier circuit arrangement in which series resistive feedback is utilized in the main amplifier to minimize distortion, and a feedback amplifier is provided in a path from the output of the arrangement to the series feedback path effectively to boost the value of the feedback resistor, a further amplifier is arranged to provide positive feedback to the resistive load circuit of the main amplifier effectively to boost the value of the resistive load.
