“…In this section, principle, operation and feature of the typical column-parallel ADCs are reviewed. Figure 3 shows a typical single-slope ADC (SS-ADC) for column implementation [2], [9]. Single-slope ADCs are very popular for a column-parallel ADC in CISs because of its very simple circuit configuration and good linearity.…”

This paper reviews architectures and topologies for column-parallel analog-to-digital converters (ADCs) used for CMOS image sensors (CISs) and discusses the performance of CISs using columnparallel ADCs based on figures-of-merit (FoM) with considering noise models which behave differently at low/middle and high pixel-rate regions. Various FoM considering different performance factors are defined. The defined FoM are applied to surveyed data on reported CISs using columnparallel ADCs which are categorized into 4 types; single slope, SAR, cyclic and delta-sigma ADCs. The FoM defined by (noise) 2 (power)/(pixel-rate) separately for low/middle and high pixel-rate regions well explains the frontline of the CIS' performance in all the pixel rates. Using the FoM defined by (noise) 2 (power)/(intrascene dynamic range)(pixel-rate), the effectiveness of recently-reported techniques for extended-dynamic-range CISs is clarified.

“…(18). The front-line of the best FoM in this definition is currently around 1.5 [(e-) 2 nJ] due to the development of CISs of Ref. [23] reported in 2017 which uses a global shutter pixel and dual-gain amplified single-slope ADC and Ref.…”
