TL;DR: This paper presents the design and test results of a fourth-order and sixth-order 14-bit 2.2-MS/s sigma-delta analog-to-digital converter (ADC) to achieve 85 dB signal- to-noise distortion ratio (SNDR) with less than 200 mW power dissipation.

14–bit, 2.2MS/s sigma delta ADCs
James C. Morizio,M. Hoke,T. Kocak,C. Geddie,C. Hughes,J. Perry,S. Madhavapeddi,M. Hood,G. Lynch,Harufusa Kondoh,Toshio Kumamoto,T. Okuda,Hideyuki Noda,M. Ishiwaki,Takahiro Miki,Masao Nakaya +15 more
TL;DR: In this paper, the design and test results of a 4th and 6th order, 14-bit, 22MS/s sigma-delta ADC were presented and the analog modulator and digital decimator sections were implemented in a 35µM CMOS, double poly, triple level metal 33v process.
