V. Ramakrishnan et al., 2.5 GB S DC COUPLED RETIMED OPTICAL TRANSDUCER WITH A DYNAMIC REFERENCE VOLTAGE COMPARATOR/, IEEE photonics technology letters, 8(5), 1996, pp. 685-687
A monolithic broad-band de-coupled Silicon bipolar optical transducer
has been designed to receive and retime uncoded data at rates up to 2.
5 Gb/s, The transducer employs a modified feedback emitter coupled log
ic (FECL) loop to dynamically set reference voltages derived from the
''1'' and ''0'' level output signals of the single-ended pre-amplifier
for balanced operation of the decision circuit, The pre-amplifier has
a nominal sensitivity of -23.1 dBm at 1 GHz.
