  • This paper details a fully programmable floating memristor (resistor with memory) emulator ASIC designed for biologically inspired memristive learning. Since real memristor is not commercially available, a compact memristor emulator is needed for device study. The designed ASIC has a memristor emulator with conductance range from 4.88nS to 4.99μS (200KΩ to 204.8MΩ). The memristor emulator is a switchedresistor based circuit with processing performed off-chip in a FPGA. The processing has been planned to be off-chip to get the freedom of programmability of any function. This paper explains the memristor emulator and the realization of synapse functionality used in neuromorphic circuits like long term potentiation (LTP), Long Term depression (LTD) and synaptic plasticity. The ASIC has been designed and fabricated in AMS 350nm process.
