Low Power flip-flops are flip-flops that are designed for low-power electronics, such as smartphones and notebooks.
 A flip-flop, or latch, is a circuit that has two stable states and can be used to store state information.
Garabed Sarkis "Garo" Yepremian (June 2, 1944 – May 15, 2015) was an American football placekicker in the National Football League for the Detroit Lions, Miami Dolphins, New Orleans Saints, and Tampa Bay Buccaneers, during a career that spanned from 1966 to 1981.
MightSat-1 was a small spacecraft developed by the U.S. Air Force's Phillips Laboratory (now part of the Air Force Research Laboratory Space Vehicles Directorate) to test technology for small satellites, including advanced dual-junction solar cells, a composite structure, a micrometeorite and debris detector, low-power electronics and a low-shock release device.
 The 140-pound satellite was launched from the Space Shuttle "Endeavour" in December 1998, during the 12th day of the STS-88 mission and performed robustly in orbit, with no spacecraft anomalies during its mission.
 Lt. Barbara Braun of the AFRL was the program manager for the satellite.
Chenming Calvin Hu () is an electronic engineer who specializes in microelectronics.
 He is TSMC Distinguished Professor Emeritus in the electronic engineering and computer science department of the University of California, Berkeley, in the United States.
 In 2009, the Institute of Electrical and Electronics Engineers described him as a “microelectronics visionary … whose seminal work on metal-oxide semiconductor MOS reliability and device modeling has had enormous impact on the continued scaling of electronic devices”.
Arthur Frank Witulski is an American electrical engineer.
 He is the Research Associate Professor Electrical Engineering and Computer Science at Vanderbilt University.
 where his research activities focus on microelectronics and semiconductor devices.
 He is affiliated with the Radiation Effects and Reliability Group at Vanderbilt University where he works on the effects of radiation on semiconductor devices and integrated circuits.
 He also serves as an engineer at the Institute for Space and Defense Electronics at Vanderbilt.
 He is best known for his work in the field of Power electronics and ionizing radiation response of DC-to-DC converter.
Low-power electronics are electronics that have been designed to use less electric power, e.g. notebook processors.
Massoud Pedram (Persian: مسعود پدرام‎ ‎ ) (born in Ahvaz) is an Iranian American computer engineer noted for his research in green computing, energy storage systems, low-power electronics and design, electronic design automation and quantum computing.
William George Capece (born April 1, 1959 in Miami, Florida) is a former professional American football player who played placekicker for three seasons for the Tampa Bay Buccaneers.
 He attended Chaminade-Madonna College Preparatory School in Hollywood, Florida along with David Shula, and was invited by Shula's father, Miami Dolphins coach Don Shula, to attend Dolphin practices and work out with placekicker Garo Yepremian.
 It was Yepremian who provided Capece with the encouragement to consider a career in professional football.
 Capece attended Florida State University, where he graduated as the holder of FSU's records for single-season scoring (104 points), most field goals in a game (five, against Pittsburgh), and field goal percentage (100%).
 His 104 points in 1980 were the most by a kicker in national collegiate history.
 He was signed to a professional contract with the Buccaneers in 1981, during a week in which the Buccaneers cut both their placekicker and their punter.
 Ironically, Capece's signing marked the end of his former mentor's career, as Yepremian was the player he was signed to replace.
 After a late-1983 loss to the Green Bay Packers in which missed kicks provided the margin of defeat, coach John McKay made his famous announcement that "Capece is kaput".
 Capece returned as the team's placekicker the following season, but was waived following a poor performance in a preseason game against the Dolphins.
 His 41 field goals stood as the Buccaneers' career record until broken in 1987 by Donald Igwebuike.
Dr. Edward Keonjian (14 August 1909 – 6 September 1999) was a prominent engineer, an early leader in the field of low-power electronics, the father of microelectronics.
 In 1954 Keonjian designed the world's first solar-powered, pocket-sized radio transmitter.
 In 1959 Keonjian designed the first prototype of integrated circuit.
 In 1963 he organized the world's first international symposium on low-power electronics.
 Later on Keonjian collaborated with NASA astronaut Neil Armstrong as chief of failure analysis on the Apollo 11 project.
Wolfgang Fink is a German theoretical physicist.
 He is currently an Associate Professor and the inaugural Edward & Maria Keonjian Endowed Chair of Microelectronics at the University of Arizona.
 Fink has joint appointments in the Departments of Electrical & Computer Engineering, Biomedical Engineering, Systems & Industrial Engineering, Aerospace & Mechanical Engineering, and Ophthalmology & Vision Science at the University of Arizona.
