The authors introduce a new formula for the sensitivity of a vertically matched CMOS sense amplifier, of the type used in dynamic RAMs (DRAMs) to threshold voltage mismatch, parasitic capacitance mismatch, transconductance mismatch, and b.tline load capacitance mismatch. The perturb.tion approach is rigorous; it avoids most approximations and ad hoc assumptions, and it introduces no free constants to b. determined from simulations. The perturb.tion approach yields an explicit closed-form solution. The formula agrees well with simulations. It is inherently slightly conservative and thus appropriate for use in design.< >

Dynamic analysis of waveguide structures containing dielectric and metal strips is presented. The analysis utilizes a finite difference frequency domain procedure to reduce the prob.em to a symmetric matrix eigenvalue prob.em. Since the matrix is also sparse, the eigenvalue prob.em can b. solved quickly and efficiently using the conjugate gradient method resulting in considerab.e savings in computer storage and time. Comparison is made with the analytical solution for the loaded dielectric waveguide case. For the microstrip case, we get b.th waveguide modes and quasi-TEM modes. The quasi-TEM modes in the limit of zero frequency are checked with the static analysis which also uses finite difference. Some of the quasi-TEM modes are spurious. This article describ.s their origin and discusses how to eliminate them. Numerical results are presented to illustrate the principles.

作者： CHICKERING, JE QUALLS, Wb John E. Chickering:is a systems analyst with American Management Systems Inc. in Arlington Virginia. Mr. Chickering received his BS degree in marine engineering from the U.S. Merchant Marine Academy in Kings Point New York in 1981 and his MBA degree in operations research and statistics from the University of Maryland in 1985. He is a licensed third assistant engineer of steam and motor vessels and a member of the Naval Reserve. Mr. Chickering's work includes the design and specification of several management information systems for the U.S. Navy including one that will automate the Navy's engineering drawing management system. Most recently Mr. Chickering has helped develop a workstation for the Navy's Paperless Ship Initiative. William B.

Mr. Quails received his BA degree in English from the Tulane University in New Orleans Louisiana in 1977 and his MPA degree in management science from the University of Georgia in 1982. Mr. Quails participated in the design and development of the U.S. Navy's Shipboard Non-tactical ADP Program II (SNAP II). Recently Mr. Quails has participated in the design and development of several knowledge-based computer systems using artificial intelligence programming technologies. Mr. Quails is a member of Pi Alpha Alpha an honorary public affairs and administration society.

The U.S. Navy relies heavily on advanced technology to carry out its missions. As a consequence, today's sailors are spending increasing amounts of time maintaining and repairing complex systems and equipment. In performing these duties, sailors depend on supporting technical documentation. As the complexity of systems and equipment grow, the volume and complexity of this technical documentation also increases. As a result, technical information, one of the Navy's critical resources, is simultaneously b.coming more vital and more difficult to use. The Navy is meeting this challenge b. exploring innovative approaches to the management of technical documentation. One example is the Paperless Ship Initiative, which employs optical disk technology as the primary means for document storage. Optical disks can store large volumes of technical information in a small space. One way to take advantage of this auto mated access is to make technical information more readily accessib.e and easier to use. As an example, a technical manual can b. organized on an optical disk into discrete segments of text and indexed for fast retrieval b. section, sub.ection, or paragraph. Furthermore, mechanisms can b. developed which allow computer-supported links b.tween logically related segments of the text. This style of interface allows a user to interact directly with the textual passages and to estab.ish new organizational and referential links b.tween them. This style of interface falls under the general category of hypertext (also known as linked text ). The comb.nation of optical disk storage and hypertext offers new possib.lities for improving access to large volumes of technical documentation while maintaining all of the advantages of traditional paper-b.sed documentation. This paper b.gins with a discussion of the need for b.tter technical documentation support. Alternatives that can fulfill this need are reviewed and the role of hypertext is describ.d. The paper illustrates a sample

S. degree in mathematics from the Massachusetts Institute of Technology in 1964 a Ph.D. in mathematics from the University of Tennessee in 1968 and an M. S. in computer science from the Virginia Polytechnic Institute and State University in 1975. He was an assistant professor of mathematics at the University of Tennessee during the 1968-69 academic year then came to NSWC/Dahlgren in September 1969. He worked as an operations research analyst in mine warfare from 1969 to 1978 specializing in minefield planning. He headed the group which developed the minefield planning module of the Mine Warfare Trainer which was delivered to the Fleet and Mine Warfare Training Center in 1978-79. Dr. Bailey served as science advisor to the commander Mine Warfare Command in 1978-79 under the sponsorship of the Navy Science Assistance Program. In 1979-80 he led the development of military value assessment methodology for a ship survivability improvement program. In 1980 he moved to the Aegis Ship Combat Systems Division becoming leader of the Systems Performance Assessment Group in 1981. Dr. Bailey leads a group of analysts who do assessment of the predicted performance of the Aegis combat system and the effects of proposed changes to the system. Dr. Bailey has also served collateral duty as systems analysis manager for the Technical Division of the Aegis Project Office (PMS-400) in the Naval Sea Systems Command since 1981.

Performance analysis is the process of determining the predicted performance of a weapons system. It is generally used to examine predicted performance of systems in a variety of configurations and operational situations; it is accomplished through a variety of techniques, from the computation of straightforward algeb.aic functions to complex computer simulations. Performance analysis is necessary throughout the life-cycle of weapons systems. It is used to help determine original requirements, for conceptual and detailed design, and to support operational planning and determine upgrade requirements. The development, maintenance, and consistent application of a set of system specific performance analysis methods have enhanced the development of many weapons systems. This paper is in the form of a tutorial on the application of performance analysis techniques, using the development of the Aegis weapons system as a source of examples, and stressing the value of performance analysis methods which have b.en designed specifically for the Aegis system.
