10-Gsample/s Optoelectronic A/D Converter
13 November 2003
A 5-bit,10-GSample/s flash A/D converter (ADC) is fabricated for 10-Gb/s optical receivers. To achieve a 10 GSample/s rate with wide signal bandwidth, our design focus on reducing aperture uncertainty, clock skew, and metastability error. The ADC achieves a 4.1 effective bits at low input frequencies and 2.8 effective bits at 4.9-GHz input signal at 10Gsample/s.
