Akter, S. (author), Makinwa, K.A.A. (author), Bult, K. (author)This paper presents a new dynamic residue amplifier topology for pipelined analog-to-digital converters. With an input signal of 100 mV<sub>pp,diff</sub> and 4 × gain, it achieves-100-dB total harmonic distortion, the lowest ever reported for a dynamic amplifier. Compared to the state of the art, it exhibits 25 dB better linearity with twice...journal article 2018

Akter, S. (author), Sehgal, R.K. (author), van der Goes, Frank (author), Makinwa, K.A.A. (author), Bult, K. (author)This paper presents a closed-loop class-AB residue amplifier for pipelined analog-to-digital converters (ADCs). It consists of a push-pull structure with a ``split-capacitor'' biasing circuit that enhances its power efficiency. The amplifier is inherently quite linear, and so incomplete settling can be used to save power while still...journal article 2018
