A method for improving the sensitivity (or speed) of a master-slave emitter-coupled logic comparator using emitter degeneration resistors is presented. The degeneration resistors in the latching pair reduce the transistor charging time, thus allowing more time for regeneration. Improved and standard comparators were implemented using the InP/GaInAs… (More)
A transimpedance amplifier (TIA) in 1-μm InP technology for the application in next generation fiber optical data communication systems is presented. The TIA exhibits a bandwidth of 45 GHz, a differential transimpedance of 70dBOhm and a total harmonic distortion (THD) below -30 dB up to a differential output voltage of 500mV-PP.
