Abstract
A dual operating mode 8b, 1.1V, 120MHz/250MHz, 9.4mW/22.8mW pipeline ADC for Gb Ethernet applications is presented. Considering 60MHz of signal bandwidth in both operating modes, the ADC achieves a peak SNDR of 44.1dB/40.7dB (7b/6.5b ENOB), featuring a minimum FoM of 0.84pJ/conv at 120MHz and 2.2pJ/conv at 250MHz. A 90nm CMOS technology was used to integrate the ADC whose active area is 1.25×0.65mm 2 .
