An amplifier circuit includes an amplifier stage () having an amplifier transistor () with a gate coupled to an input () of the amplifier stage, a source coupled to a reference connection (gnd) and a drain coupled to a positive power supply connection (V+). The amplifier circuit includes a bias stage () having a bias transistor (), a drain resistance () and a source resistance (). The bias transistor includes a gate coupled to a negative power supply connection (V&#x2212;), a source coupled to the negative power supply connection (V&#x2212;) via the source resistance and a drain coupled to the reference connection via the drain resistance and to the gate of the amplifier transistor. The bias stage includes a further resistance () coupled from a node between the source of the bias transistor and the source resistance of the bias transistor to a circuit node that carries a voltage higher than the voltage at the negative power supply connection.
