Abstract: We propose a 14.3-bit extended counting ADC with built-in binning function for medical X-ray CMOS imagers.
To reduce the area and improve the image resolution simultaneously, the proposed ADC internally performs the analogue
binning operation without a charge amplifier. The ADC also uses an extended input range to realize true 14-bit dynamic
range when applying the digital correlated double sampling technique. The proposed ADC was fabricated using a 0.35-μm
CMOS process and the measured differential and integral non-linearities of the 14.3-bit ADC are +0.97/-0.79 and +2.79/-1.70
