4/21/2016: AEi Systems Gives Paper on DDR Regulators at Space Power Workshop
Steve Sandler will be presenting a paper on DDR Termination Regulators at the 2016 Space Power Workshop in Manhattan Beach CA.
The DDR termination regulator is the most complex regulator application to date, pushing the boundaries of performance with possibly insurmountable stability issues. In this presentation we’ll consider the linear termination regulator solution and the complexity of the stability issue. Using a custom developed DDR termination regulator measurement board, measurements are performed to show the non-linearity and stability issue as well as the complexity of determining the maximum voltage excursion. The paper will be given on Thursday April 21 at 8am, so please make plans to be there early.

AEi Systems Achievement on GPS IIF Clock Worst Case Circuit Analysis
Boeing Representatives with the AEi Systems Team
(5/16/2012) During 2012, representatives from Boeing visited AEi Systems’ offices
in Los Angeles in order to recognize AEi Systems’ achievement with respect to its
worst case circuit analyses assessment of Excelitas’ Rubidium Frequency Standard
(RFS) atomic clock, a critical portion of the U.S. Air Force’s Global Positioning
System (GPS IIF).
The Boeing-led team developing GPS IIF completed the program’s worst case assessment on Dec. 20, 2011, on schedule, and is now proceeding rapidly in the program’s manufacturing phase.
“AEi Systems is very pleased to have supported the GPS IIF team and performed the analysis, modeling, and testing of such an important piece of the GPSIIF satellite,” noted Charles Hymowitz, managing director of AEi Systems. “We are also pleased to continue our tradition of close cooperation with Excelitas, Boeing, and all other subcontractors involved with this exciting project and look forward to assisting on future versions of the GPS program.”
GPS IIF supports the current GPS II infrastructure, including position, navigation and timing services for more than 750 million users around the globe. The Excelitas designed and manufactured RFS is a critical portion of the GPSIIF program because GPS satellite technology is inherently dependent on the availability of an extremely accurate and highly stable onboard frequency source.
WCCA is performed to improve design reliability and to establish that a product’s performance has a design capable of meeting its specifications throughout its entire operational life. In addition to WCCA, AEi Systems specializes in circuit stress and derating analysis, failure mode effects criticality analysis (FMECA), reliability/mean time between failures (MTBF) analysis, and SPICE modeling, especially in the area of power systems and devices for applications in the medical, military, space, nuclear, and other industries where high reliability is required.
AEi Systems is the world leader in SPICE modeling; worst case, failure, and reliability analysis; and power systems analysis and design. Founded in 1995, AEi Systems has a hard-earned reputation for delivering its products and services on time, under budget, and to customer specifications, and serves nearly every significant IC and aerospace manufacturer and many of their customers.
