The popularity of internet and multimedia has greatly increased the demand for high-speed transmission networks. The next generation of optical networks will Likely request fast packet switching to support multimedia applications. In fact, in such applications, the amplitude and phase of the receiver can be quite different from packet to packet due to different fiber attenuation and the chromatic dispersion caused by the variation of the transmitter's wavelength. Link performance is strongly dependent on both the sensitivity and dynamic range of the receiver circuit. Although emerging lightwave communication technologies are brining 10 Gb/s systems into commercial use [K. Yukio, A. Yuji, N. Kiyoski, K. Hiroyuki, and Y. Imai, IEEE Trans. Microwave Theory Tech. 43, 1916 (1995)], optoelectronic interfaces an still limiting factors for better performances. In this article, we address power penalty in high-speed burst-mode operation. Architectures applicable to high-speed systems and insensitive to parasitic input loading are proposed to overcome speed limitations at the receiver's input. A 4.7 GHz bandwidth, a transimpedance of 43 dB Omega and an average input noise current density of 9 pA/root Hz have been achieved in simulations with the single-ended version.
