This paper presents a circuit in which tungsten oxide -based analog memristors are post-processed on a CMOS-based Field-Programmable Analog Array Integrated Circuit (FPAA-IC). FPAAs are powerful tools for rapid analog experimentation, prototyping and power-efficient computing, and they allow custom analog circuits to be built and reconfigured. The primary motivation for this work is to introduce and...
We show resistive switching effects in memristive devices exhibit significant stochasticity. When the switching is dominated by a single filament, the switching time is fully random and shows a broad distribution. However, the switching distribution can be predicted and responds well to controlled changes in the programming conditions. The native stochastic characteristic can be used to generate random...
We show a Field-Programmable Analog Array complemented with post-processed memristors (FPAA/memristor hybrid circuit), and present it as a platform for analog signal processing. The FPAA is fabricated on CMOS and uses floating-gate transistors (FGT) to realize programmable wiring fabrics and analog computing resources. The memristors, post-processed on top of the FPAA, are analog, which means that...
