MIL-HDBK-1331 Parameters To Be Controlled For The Specification Of Microcircuits, Handbook ForThis handbook describes the parameters required as a minimum for the specification of microcircuits. Parameters, rather than circuits, are considered because circuits vary with the manufacturers involved. Further, circuit designs should be subject to change if improvement results as long as the affected designs are compatible and fully interchangeable. The specific objectives of this document are as follows: a. To provide the minimum parameters that should be specified to ensure adequate evaluation of circuit design and performance. b. To provide maximum commonality of parameters for purpose of test and measurement, within and between major classes of microcircuit types and to allow the recognition of interface problems between types of microcircuits. c. To provide standard abbreviations, definitions and symbols pertinent to the specification of microcircuits. d. To promote maximum interchangeability and compatibility between microcircuits types.

APPENDIX A

A.5.2.34  Differential input impedance (zid).  The small-signal impedance between two ungrounded input terminals of a differential amplifier.

A.5.2.35  Single-ended input impedance (zis).  The small-signal impedance between one input terminal of a differential amplifier and ground with the other input terminal AC grounded.

A.5.2.36  Differential output impedance (zod).  The small-signal impedance between two ungrounded output terminals of a differential amplifier.

A.5.2.37  Single-ended output impedance (zos).  The small-signal impedance between one output terminal of a differential amplifier and ground with the other output terminal AC grounded.

A.5.2.38  Input bias current temperature sensitivity (dIIBfdT).  The ratio of the change in the input bias current to the change in circuit temperature for a constant output voltage.  This is an average value for a specified current range.

A.5.2.39  Input offset current temperature sensitivity (dIIOfdT).  The ratio of the change of input offset current to the change of circuit temperature for a constant output voltage.  This is an average value for a specified current range.

A.5.2.40  Input offset voltage temperature sensitivity (dVIOfdT).  The ratio of the change of input offset voltage to the change in circuit temperature for a constant output voltage.  This is an average value for a specified temperature range.

A.5.2.41  Phase margin (om).  A figure equal to 180 degrees minus the absolute value of the phase shift measured around the loop at that frequency at which the magnitude of the loop gain is unity.
