Electronics and Instrumentations

The mission of the group is performing the state of the art researches to fulfill some national demands and also nativation some of the most advanced electronic technologies in the country. For this reason the activities of the electronic group has been focused on three main existing axes in electronic field:

-Electronic instrumentation
-Application of signal processing in nondestructive testing of material
-Design and implementation of industrial integrated circuits

Electronic instrumentation
Electronic instrumentation systems depending on the information type utilize the knowledge and technology of fields such as physics, chemistry, mechanics, electronic and informatics. The mechanism of this system is like this: First the raw information is sensed by sensors. Depending on the nature of information one of the signal processing methods or a hybrid of them is applied. Some of the activities are as follows:

  • Design, implementation, installation and commissioning of instrumentation systems

    • Design, implementation, installation and commissioning multi-disciplinary instrumentation systems (physics, chemistry, mechanics, material sciences, electronics, informatics)

    • Design and implementation of portable electronic systems to be used in aggressive and industrial environments.

    • Design and implementation of multi-processor systems containing DSPs and FPGA

    • Design of medical instruments

    • Design of Interfaces for Electronics Control Unit (Automotive Electronics)
       

  • Electronic war systems
    With the development of efficient electronic systems whole over the world and application of them in different organizations such as industry and armed forces, the electronic war in all of its faces and with extraordinary importance has shown itself. So because of demands for doing research and signal processing design the electronic research center has made so many important and eye catching contractions in electronic war industry with the purpose of development and self sufficiency. Some of the finished activities are:

    • ESM systems

    • ECM systems

    • IFM systems
       

  • Test & analysis of industrial and medical systems

    • Test and analysis of functionality control and predictioned work on large scale systems

    • Measurement in harsh environments (high temperature, moisture, shock, pressure)

    • Quality control of industrial products in the production process and tracking their evolution for constructing them under the international standards

    • Test and analysis of functionality control and prediction work on medical instruments.

    • Consultancy in the field of medical equipment standards

Application of signal processing in nondestructive testing of material

  • Feasibility study of intelligent flaw detector system with ultrasonic waves for nondestructive testing of petroleum pipelines

  • Developing and putting forward the proposal of the construction of an industrial prototype of an intelligent flaw detector system based on magnetic flux for the nondestructive testing of gas and petroleum pipelines

  • Design and build of a laboratory prototype of a magnetic flux based flaw detector

  • Design and build of a laboratory prototype of an eddy current based flaw detector

  • Design and build of laboratory prototype of an ultrasonic flaw detector

  • Application of ultrasonic signals, eddy current and magnetic flux leakage in nondestructive testing of materials

Design and implementation of industrial integrated circuits
In recent two decades the demands of public and specialist users of electronic systems have been increased so much. The electronic system must have got diverse features: the capability of performing several tasks simultaneously, smallness, low power consumption, invulnerable against disturbances and environment noise, reliability and reasonable production cost. Some of the finished activities are:

  • Design of of VLSI ICs

  • Implementation of industrial ICs

  • Design of the RSA coding circuits with methods:
    - IFM system design
    - Full custom ICs
    - Semi Custom ICs
    - ICs with pre constructed cells

  • Design of analog to digital convertor and implementation of digital signal processing blocks for biomedical signals
