As the development of odor sensors that mimic the olfactory function of biological systems progresses, we have focused on designing resistance-detection pixels that can be integrated with conventional CMOS potential-detection sensor pixels. In detection, the approach utilizes the voltage division between the odor-sensitive film and the NMOSFET, and we proposed a method to enhance sensor gain through charge transfer. In the design, we achieved the implementation of resistance-detection pixels and common wiring circuits for a 32×32 pixel array sensor. As a result, we successfully demonstrated the proposed method using verification pixels.
