Abstract

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 their conductance can be programmed in a continuous fashion. We highlight the key differences between FGTs and memristors, and discuss how analog signal processing tasks could be divided between them. Experimental results of the FPAA-memristor hybrid circuit are presented.
