A low power 6-bit flash ADC with reference voltage and common-mode calibration

A low power 6-bit ADC that uses reference voltage and common-mode calibration to improve linearity and reduce power dissipation is presented. The ADC occupies 0.13 mm
²
in 65 nm CMOS. The ADC dissipates 4 mW at 100 MS/s and 12 mW at 800 MS/s from a 1.2 V supply.
