A voltage-scalable 10-b pipelined ADC with current-mode amplifier

摘要

This paper presents an energy-efficient 10-b pipelined ADC with a current-mode amplifier. The proposed amplifier achieves high gain, low static power consumption and supply voltage scalability without any calibration or timing control. The fabricated ADC in 65-nm CMOS process achieves FOMs of 14.3-to-36.9 fJ/c-s with a supply voltage range from 0.6-V to 1.0-V.
