  • Analogue amplification device intended in particular for a laser anemometer
    Patent number: 9702891
    Abstract: An analogue amplification device comprises a first stage with a common base or gate transistor that receives the modulated input current on its emitter or its source and the output signal of this first stage corresponds to the signal of the collector, a second stage formed by a follower amplifier comprising a transistor with a common collector or drain setup, a third stage that comprises a transistor with a common emitter setup, and a fourth stage that is an amplifying stage with means allowing the realization of, on the one hand, an amplification, and on the other hand, a matching of impedance. The device can be applied to a laser anemometer with optical retro-injection.
