This paper deals with the design of a broadband low-noise receiver for fiber optical transmission systems. A high-impedance first stage is designed in order to minimize all sources of noise. Then, a second stage performs the required equalization in order to restore the signal shape, which is distorted owing to the limited bandwidth. The proposed optoelectronic receiver is theoretically analyzed. A simplified noise model is also developed. Computer simulations, performed vith MDS, are carried out, based on a complete electrical model library. The latter includes wideband noise models for normally-off and normally-on p-HEMT’s [1]. The designed low-noise amplifier exhibits a 40 dB constant trans-impedance gain over a 44 MHz-40 GHz frequency range.
