<p>The invention relates to devices in which current signals are amplified and converted into voltage signals for processing. The current signals are delivered by sensors, e.g. optical transducers, magnetical heads. The current signals are first amplified using a current to current amplifier, the amplified current signals are then transported using electrical conductors and eventually amplified using a current to voltage amplifier. The invention may find application in consumer electronic devices, cars, planes, industrial machines... An example of realisation in optical disk players is described. Such a player allows to better read altered optical disks than optical disk players known from prior art. <IMAGE></p> |
