Abstract 

A 2.2 GS/s 4 x -interleaved 6b ADC in 40 nm digital CMOS is presented. Each ADC slice consists of a 1b folding stage followed by a pipelined binary-search sub-ADC using dynamic nonlinear amplifiers for low power consumption and high speed. The folding stage samples the input, removes its common-mode component and rectifies the differential voltage. The pipelined binary-search sub-ADC leverages threshold calibration to correct for amplifier and comparator imperfections, which allows the use of inherently nonlinear dynamic amplifiers. The prototype achieves 31.6 dB SNDR at 2.2 GS/s with a 2 GHz ERBW for 2.6 mW power consumption in an area of 0.03 mm(2)
