Abstract
The present invention relates to a current amplifier including a first MOS transistor with a drain defining a first terminal for controlling the amplifier with a current and a source connected to a first supply line. It also includes a second MOS transistor with a drain forming a terminal of current output of the amplifier and a source connected to the first supply line, and at least one first bipolar transistor having a base connected to the first control terminal, an emitter connected to a gate of the first MOS transistor and is, via a first biasing resistor, connected to the first supply line and having a collector of the first bipolar transistor being connected to a second supply line.
