In particular, the front end has been fabricated using a cost-effective digital 0.18- complementary metal-oxide-semiconductor (CMOS) technology and fed with only 1 V. The prototype contains a transimpedance amplifier, a continuous-time equalizer, and an output driver. Experimentally, we have obtained 1.25-Gb/s transmission for a simple nonreturn-to-zero modulation in an optical link composed of 50 m of SI-POF and a large area Si PIN photodetector.2012http://zaguan.unizar.es/record/14898210.1109/LPT.2011.2182188http://zaguan.unizar.es/record/148982oai:zaguan.unizar.es:148982info:eu-repo/grantAgreement/ES/MICINN-FEDER/TEC2008-05455/TECIEEE Photonics Technology Letters 24, 6 (2012), 485-487byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
