• abstract: In this paper we build on our previous work on the capacitive use of OxRAM devices inside CMOS image sensors (CIS). Previously we had shown how capacitive properties of OxRAM devices can be exploited to overcome the issue of over-exposure (bright-light). In this work, we show a methodology for correction of under-exposure (dim-light). HfOx based OxRAM device is used as a programmable capacitive load in a conventional 4T-APS (active pixel sensor) circuit, simulated at 180 nm technology node. Through the proposed under-exposure correction a DR improvement of ~ 20 dB was acheived.
