Abstract

The present invention relates to an inductive sensor (1), particularly for a proximity sensor, comprising: - a resonance circuit (2) including a sensing coil (21); - an amplifier (3) comprising a first gain stage (31) and a second gain stage (32) each coupled via respective adjusting elements (33, 34) with the resonance circuit (2) to inject energy for maintaining an oscillation of the resonance circuit (2), wherein the first gain stage (31) provides a substantially linear amplification and the second gain stage (32) provides a comparator characteristics.
