Abstract
A multi-mode amplifier arrangement comprises an amplifier having a plurality of field effect transistors selectable in response to a control signal at a control terminal, said plurality of field effect transistors coupled to an input terminal to receive a signal to be amplified, said amplifier arranged between a supply terminal and a ground terminal. A tunable current source is coupled to the amplifier to provide in operation of the amplifier a constant drain current through the plurality of field effect transistors.
