Litovski V.B. Lecture Notes in Analog Electronics Testing and Diagnosis of Analog and Mixed-Signal Electronic Circuits

Springer, 2025. — 363 p. — ISBN 978-981-97-8257-4.The process of designing, manufacturing, and maintenance of electronic circuits and systems inevitably includes their testing. It is not possible to deliver a quality and reliable industrial product to the market if it is not thoroughly tested. Hence, the ability to test one’s own product is in fact a requirement to market that product. Of course, as is well known, testing does not give the manufacturer new values but only the knowledge that the products he delivers to the market are good as expected. In some situations both the manufacturer and the maintenance support are facing the need to diagnose the failure which means to find the nature and the location of the fault causing malfunction of a circuit or system. That will be also solved based on testing.
The basic ideas of testing and diagnosis are introduced. We start with the existence and physical nature of faults within the electronic circuit to establish the feeling on the necessity of testing and diagnosis. We explain here why under “testing” in this book we mainly understand test signal synthesis. We start with the fault and introduce the inductive fault analysis relating the faults and the possible failures. Functional and structural testing are contrasted and rationale for implementation the one and the other are given. Specialist’s terms such as testability, fault sensitization, detectability, observability, and similar are introduced. To diagnosis special attention is paid including a set of algorithms used for analog and mixed-signal circuits. We also introduce the notion on the importance of testing in conjunction with the price paid for it including the test sequence(s) design, implementing on testing hardware, and optimizing the speed of testing in mass production environment.
