Abstract

This paper presents a memristor based unit cell design for a readout integrated circuit (ROIC). The memristor is a nonvolatile nanoscale circuit component that has dynamic resistance dependent on the total charge applied between the positive and negative terminals. In the circuit presented, the memristor acts as the integrator in the unit cell. This eliminates the need for a large integrating capacitor. Simulations demonstrate the functionality of the unit cell, where the memristor is accurately modeled according to previously published device characterization data. The results show that memristors can potentially be used to reduce the unit cell area, which could increase the fill factor of the photodetector in single chip detector and readout designs.
