Abstract/ Executive Summary:

For quick identification of different types of faults in the electronic circuits a transistor tester is absolutely necessary. The transistor tester using a CMOS was successfully designed and constructed in the Physics Department during 1983. The meter fitted inside a polypropylene box was found to be functioning properly. A test table to identify faults was also supplied as the user guide. Major part of the work was completed in Napier College, Scotland during the stay of the research associate there for higher studies. The circuit is now in the Physics Department of BJRI, and working well condition to test transistor. the design in now gassated.

Start Date: 01-01-1983

End Date: 31-12-1983

Program Area: Farm Mechanization

Non-commodity: Performance

Objectives:

Design and construction of a transistor tester by using a CMOS integrated circuit.

Methodology:

At the beginning of the experimental procedure oscillator was constructed by using a CMOS (NAND gate) on a prototype circuit board. Secondly, the wave forms at the three identical output of the oscillator were studied. In addition, circuit action with transistor at the test socket was studied and summarized the circuit condition for different types of test. Furthermore, a single table for expressing all kinds of test results was made. Moreover, a printed circuit board was drawn and prepared and soldered the circuit components. Finally, enclosed the whole circuit board in a box.

Achievement/Findings:

The vivid result obtained in this work is the practical transistor tester which has been being used in the instrumentation works in the department of physics. In this design, a lot of work was done to eliminate enormous fault occurred in the different parts of the circuit. A transistor tester was successfully design and fabricated which is working well and kept in the physics department of BJRI.
