Amplifier circuit

A linear amplifier circuit comprises:

• differential amplification circuitry comprising:
• an input stage having first and second differential inputs, and
• an output stage, having respective first and second amplifier components with first and second differential outputs;
• wherein the first amplifier component of the output stage comprises:
• a first power transistor operably coupled to the first differential output and driven by a first differential output of the input stage, and
• a third power transistor operably coupled to the first differential output of the amplifier circuit and driven at a control electrode by a voltage at a second output of the input stage,
• wherein the second amplifier component comprises:
• a second power transistor operably coupled to the second differential output and driven by a second output of the input stage, and
• a fourth power transistor operably coupled to the second differential output and driven at a control electrode by a voltage at the first output of the input stage;
• wherein each of the first and second power transistors of the first and second amplifier components is driven in a current mirror arrangement by the respective first and second output of the input stage.
