Abstract :
A dual operating mode 8b, 1.1V, 120 MHz/250 MHz, 9.4 mW/22.8 mW pipeline ADC for Gb Ethernet applications is presented. Considering 60 MHz 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 0.84 pJ/conv at 120 MHz and 2.2 pJ/conv at 250 MHz. A 90 nm CMOS technology was used to integrate the ADC whose active area is 1.25 times 0.65 mm2.
