It is also envisaged to present the working of embedded neural hardware as associative memory and self-organizing maps.

An overview of the necessary components is presented, as well as a design for a pulse-width modulation oscillator capable of transforming a current input (which represents the squashed, post-synaptic signal processed by a particular neuron) into the probability associated with the binary state of that neuron. A CMOS hardware prototype has been designed and fabricated, and precautions were taken during the design and simulation stages in order to prevent the oscillators on the same chip from locking together. Apart from testing the hardware prototype, future plans involve the hardware implementation of other modules, such as the synapse, the squashing function and weight changing circuitry.","PeriodicalId":191273,"journal":{"name":"Proceedings of the Seventh International Conference on Microelectronics for Neural, Fuzzy and Bio-Inspired Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132063150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, I recreated retinal microcircuits in a chip, Visio1, that models the four predominant ganglion-cell types. It has 104/spl times/96 photoreceptors, 4/spl times/52/spl times/48 ganglion-cells, a die size of 9.25/spl times/9.67 mm/sup 2/ in 1.2 /spl mu/m 5V CMOS, and consumes 11.5 mW at 5 spikes/second/neuron. Visio1 includes novel subthreshold current-mode circuits that use horizontal-cell autofeedback to decouple spatiotemporal bandpass filtering from local gain control and use amacrine-cell loop-gain modulation to adapt highpass and lowpass temporal filtering. Different ganglion cells respond to motion in a stereotyped sequence, making it possible to detect edges of one contrast or the other moving in one direction or the other. The author presents results from a multichip 2-D motion architecture, which implements Watson and Ahumada's model of human visual-motion sensing.","PeriodicalId":191273,"journal":{"name":"Proceedings of the Seventh International Conference on Microelectronics for Neural, Fuzzy and Bio-Inspired Systems","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126067145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The devices were part of a neural prosthesis that allows simultaneous multichannel recording and multisite stimulation of neurons. Overcoming the brittle mechanics of silicon devices and challenging housing demands close to the nerve, we established a process technology to fabricate light-weighted and highly flexible polyimide based devices with integrated interconnects. A new assembling technique-the microflex interconnection (MFI)-has been applied for the connection of the flexible microsystems to silicon microelectronics. In this paper, we present different shapes and applications of the flexible electrodes.

Visual readout by attachment of an embedded system comprising dedicated image sensor, processor, and transmission system as an add-on to existing installed meters is an interesting alternative to the expensive replacement by electronic meters with remote readout. With regard to the underlying large number of potential installation sites, this problem is also an instance of an application where a dedicated implementation can compete with general purpose hardware concerning size and costs. In our approach, we focuses on the compact, cheap, and energy conserving implementation of a neural embedded system for this application.

This paper presents accurate, discrete-time CMOS building blocks to implement learning rules on-chip. Specifically, a voltage mode high precision comparator as well as an absolute value circuit. These blocks, plus multiplexing in time techniques, are used to build a circuit to determine the polarity of the learning increments. Compactness and low power consumption have been considered the main requirements, since they are essential to increase the complexity of the neural systems. An example circuit has been simulated with HSPICE with the parameters of a 1 /spl mu/m CMOS technology. Statistical variations of technological parameters were considered. The results show that all curves from 30 runs of a Monte Carlo analysis behave as expected, and at least 8 bits of resolution is achieved by the proposed techniques.","PeriodicalId":191273,"journal":{"name":"Proceedings of the Seventh International Conference on Microelectronics for Neural, Fuzzy and Bio-Inspired Systems","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121488196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
