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. info:eu-repo/grantAgreement/ES/MICINN-FEDER/TEC2008-05455/TEC info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.919 2011 ENGINEERING, ELECTRICAL & ELECTRONIC 137 / 245 = 0.559 2011 Q3 T2 NANOSCIENCE & NANOTECHNOLOGY 55 / 66 = 0.833 2011 Q4 T3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gaberl, Wolfgang Zimmermann, Horst 5008 250 Universidad de Zaragoza Dpto.
