Inhalt:
The design of very high speed broadband latched comparators in 0.13-µm SiGe bipolar technology is presented. The comparators are used as a broadband front-end of a 1-tap decision feedback equalizer (DFE) for 100 Gb/s optical communication. Techniques for measuring the bandwidth of the designed comparators are presented. Measurement results show a 3 dB bandwidth of about 45.5 GHz. A half rate parallel lookahead architecture is used for the implementation of the DFE with modifications to relax the timing constraints of its components.
