Aznar, Francisco (Universidad de Zaragoza) ; Gaberl, Wolfgang ; Zimmermann, Horst

Resumen: A new transimpedance amplifier (TIA) for 2.5 Gb/s optical communications fabricated in a standard 0.18 μm CMOS process is presented. The proposed TIA is based on a conventional structure with an inverting voltage amplifier and a feedback resistor, but incorporates a new technique to enhance the input dynamic range and to prevent the TIA from saturation at high input currents. According to electrical characterization the receiver shows an optical sensitivity of −26 dB m for a BER=10−12, assuming a responsivity of 1 A/W, and an optical power dynamic range above 26 dB. The power consumption of the core is only 10.6 mW at a single supply voltage of 1.8 V.
