An input stage for an optical receiver with a photodiode (T), which has its output connected, via a capacitor (C1), to the input of a transimpedance amplifier (f), includes a unit having a resistance depending on the voltage, which is connected between the output of the photodiode and the earth potential of the amplifier. The photodiode is a PIN diode, and said unit with a voltage dependent resistance includes a feed-back amplifier (Df) with a frequency response adapted to that of the transimpedance amplifier. |
