Abstract
An amplifier has a voltage to current converter coupled between a first potential and a reference potential and includes a control input coupled to a voltage at an input of the amplifier for converting the voltage at the amplifier input into a corresponding output current. A current multiplier is fed by the output current for producing an increased current. The increased current is fed to a control electrode of a transistor. A feedback element provides the first potential to the voltage to current converter by coupling a voltage produced by the feedback element in response current through the transistor to the voltage to current converter.
