Abstract :
This work reports on alternative methods of improving photoreceiver sensitivity as well as gain-bandwidth product in a high-capacity optical transmission system. A wide-band and controllable-gain preamplifier utilizing parallel feedback and the capacitive peaking technique which can enhance the bandwidth and can control the gain keeping output DC voltages constant is presented. PSPICE simulations using a 0.6 μm GaAs process give 1.097 GHz bandwidth, 87 dBohms transimpedance gain, 4.5 pA/[Hz]1/2 average equivalent input noise current spectral density and 55 mW power consumption
