Based on the HSPICE (circuit program) simulation results, approximated empirical equations for analyses were formulated. The proposed chaotic neuron model integrated circuit consists of several op-amps, sample and hold circuits, a nonlinear function block for chaotic signal generation, a clock generator, a nonlinear output function, etc. This paper presents a fully integrated circuit implementation of an operational amplifier (op-amp) based chaotic neuron model with a bipolar output function, experimental measurements, and analyses of its chaotic behavior. This paper describes a unique aspect of the design and computer simulation results of the ASIC. Such devices are inherently radiation-hard and have PNP transistors whose performance is superior to the lateral geometry types.

The more » design is implemented with dielectrically isolated, vertical geometry transistors.

Each of the eight channels can be biased or enabled separately. The output stages employ power devices configured as class AB and are capable of driving 50-ohm loads. The input stages employ a common-collector/common-base topology for good bandwidth and slew characteristics. annual conference on nuclear and space radiation effects, Monterey, CA, USA, Other Information: Portions of this document are illegible in microfiche products Country of Publication: United States Language: English Subject: 46 INSTRUMENTATION RELATED TO NUCLEAR SCIENCE AND TECHNOLOGY OPERATIONAL AMPLIFIERS PHYSICAL RADIATION EFFECTS GAMMA RADIATION HOT CELLS INTEGRATED CIRCUITS IRRADIATION NEUTRONS RADIATION DOSES AMPLIFIERS BARYONS DOSES ELECTROMAGNETIC RADIATION ELECTRONIC CIRCUITS ELECTRONIC EQUIPMENT ELEMENTARY PARTICLES EQUIPMENT FERMIONS HADRONS IONIZING RADIATIONS LABORATORY EQUIPMENT MICROELECTRONIC CIRCUITS NUCLEONS RADIATION EFFECTS RADIATIONS 440200* - Radiation Effects on Instrument Components, Instruments, or Electronic SystemsĪ monolithic eight-channel preamplifter for spaceborne nuclear instrumentation is being developed using a semi-custom Application Specific Integrated Circuit (ASIC) based on bipolar tile-array technology, This general purpose charge sensitive preamplifier was designed using a complimentary current mirror approach so that it would be useful for amplifying both positive-going and negative-going input pulses while consuming low to moderate power. of Electrical Engineering Hewlett-Packard Co., Corvallis, OR (USA) OSTI Identifier: 5485168 Report Number(s): CONF-850711-12 ON: DE85015660 DOE Contract Number: AC05-84OR21400 Resource Type: Conference Resource Relation: Conference: 22.
