7.4 Reliable Circuit
This section cannot possibly cover all of the aspects of circuit
design. In addition to a number of design textbooks, there are handbooks
available (e.g., References  and
) which can be used to solve almost any circuit design problem.
The only thing that this section can accomplish in the limited
space available is to outline some of the circuit design methods available to
ensure high reliability. They are by no means comprehensive; circuit designers
should consult their own organizationsí design rules, component application
notes, the cited references and other relevant sources. The methods outlined
in this section are intended as a guide to the points which reliability
engineers and circuit designers need to consider.
In order to produce a reliable circuit design, the designer must
consider the following reliability design criteria:
||Component derating (discussed in the
||Proper use of parts (discussed in 7.2)|
||Transient and overstress
||Parameter degradation and
Except for component derating, which was discussed in the
previous section and parts use, which was discussed in 7.2, the following paragraphs
discuss each of the listed criteria.
