Item type:Publication, Access status: with files , Integrated circuit with memristor emulator array and neuron circuits for biologically inspired neuromorphic pattern recognition(World Scientific Publishing (WSPC), 2017-04-27); ; ; ; This paper details an application-specific integrated circuit (ASIC) with an array of switched-resistor-based memristors (resistor with memory) and integrate & fire (I & F) neuron circuits for the development of memristor-based pattern recognition. Since real memristors are not commercially available, a compact memristor emulator is needed for device study. The designed ASIC has five memristor emulators with one having a conductance range from 4.88ns to 4.99μs (200kOhm) to 204.8MOhm)) and other four having conductance ranging from 195ns to 190μs (5.2kOhm) to 5.12MOhm)). Signal processing has been planned to be off-chip to get the freedom of programmability of a wide range of memristive behavior. This paper introduces the memristor emulator and the realization of synapse functionalities used in neuromorphic circuits such as long term potentiation (LTP), Long Term depression (LTD) and synaptic plasticity. The ASIC has two I & F neuron circuits which are intended to be used in conjunction with memristors in a multiple chip network for pattern recognition. This paper explains the memristor emulator, I & F neuron circuit and a respective neuromorphic system for pattern recognition simulated in LTspice. The ASIC has been fabricated in AMS 350nm process.Publicationtype: Journal ArticleScopus© Citations 11 372 470 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Programmable memristor emulator ASIC for biologically inspired memristive learning(2016-11-28); ; ; ; 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.Publicationtype: Conference Paper66 - Some of the metrics are blocked by yourconsent settings
