Amplifying circuit
The invention concerns an amplifier having an output stage with a complementary pair of first and second transistors (106, 108) each coupled to an output node (104) of the amplifier; control circuitry (110, 114, 116, 118) arranged to provide a control signal at a control node of the first transistor...

| Zusammenfassung: | The invention concerns an amplifier having an output stage with a complementary pair of first and second transistors (106, 108) each coupled to an output node (104) of the amplifier; control circuitry (110, 114, 116, 118) arranged to provide a control signal at a control node of the first transistor based on the voltage at an input node (102) of the amplifier; and adjustment circuitry (210) arranged to adjust the control signal to maintain the current through the first transistor above a minimum value (I MIN ). |
