28.6 A 78.5dB-SNDR radiation- and metastability-tolerant two-step split SAR ADC operating up to 75MS/s with 24.9mW power consumption in 65nm CMOS

Abstract

High-resolution, low-power radiation-tolerant ADCs are under great demand from medical, aerospace and high-energy physics applications. In the ATLAS Liquid Argon Calorimeter of the LHC experiment at CERN, the radiation operation condition coupled with the large dynamic range (>12b ENOB), 40-80MS/s sample rate and low power (for cooling system requirement) specs [1] make the design of such ADCs a very challenging task.
