Abstract
An amplifier (100) has first and second operation modes. The amplifier (100) includes an amplifier input portion (110) and an amplification gain stage. The amplification stage has two gain paths (120, 140) coupled in parallel to the amplifier input portion (110). At least one of the gain paths (120) has an amplification component (121) that in part forms a switch to select between the first and second operation modes.
