Abstract
The invention concerns an amplifier circuit comprising: an amplifier having a first input coupled to an input node of the amplifier circuit via a first resistor and an output coupled to a load via a coupling capacitor, the output being coupled to the first input via a second resistor; and a current ramp generator adapted to supply a current ramp to the first input of the amplifier during a power up phase or power down phase of the amplifier circuit to control the rate of charge or discharge of the coupling capacitor.
