RECEIVER OF A PULSED LIGHT SIGNAL WITH WIDE DYNAMIC RANGE |
| 摘要 |
A receiver of a pulsed light signal comprises a photodiode adapted to generate an electric current in response to this light signal, having a parasitic capacitance Cd as its characteristic; an electrical ground; and a transimpedance amplifier connected to the input of the photodiode by a linking capacitor Cliaison. It includes an attenuation pad located between the photodiode and the transimpedance amplifier, consisting of a capacitor Cp where Cp=Cd/(α−1), α being a predetermined attenuation, where α>1. |

1. A receiver of a pulsed light signal comprising:
a photodiode adapted to generate an electric current (ID) in response to this light signal, having a capacitance Cd as its characteristic, an electrical ground, and a transimpedance amplifier connected to the input of the photodiode by a linking capacitor Cliaison, and an attenuation pad located between the photodiode and the transimpedance amplifier, consisting of a capacitor Cp where Cp=Cd/(α−1), a being a predetermined attenuation, where α>1. |
