Abstract
Amplifier comprising an input signal node for conveying an input signal having an input signal value and an output signal node for conveying an output signal having an output signal value. Amplifier circuitry is coupled to the input signal node and provided with a plurality of intermediate output signal nodes, each for conveying an intermediate output signal having an intermediate output signal value. The intermediate output signal value in each intermediate output signal node relates to the input signal value in accordance with predetermined signal gains. A signal selector selects one of the intermediate output signals and feeds the selected one to the output signal node. The amplifier may be comprised in an analogue to digital converter. The amplifier may be incorporated in a down hole tool. The method of amplification may be used in a method of producing a mineral hydrocarbon fluid.
