Low Power Microelectronics: Retrospect and Prospect
The era of low power microelectronics began with the invention of the transistor in the late 1940’s and came of age with the invention of the integrated circuit in the late 1950’s. Historically, the most demanding applications of low power microelectronics have been battery operated products such as wrist watches, hearing aids, implantable cardiac pacemakers, pocket calculators, pagers, cellula...
متن کاملRadiation Tolerant Ultra Low Power CMOS Microelectronics: Technology Development Status
Electronic components used in spacecraft are susceptible to the radiation environment that causes detrimental effect which could jeopardize the mission. Much effort has been devoted to methodologies that would produce radiation tolerant or hardened devices hopefully with speed-power performance close to commercial parts. Recent development in combining radiation tolerance by design technique wi...
متن کاملEmbedded power supply for low-power DSP
The use of dynamically adjustable power supplies as a method to lower power dissipation in DSP is analyzed. Power can be reduced substantially without sacrificing performance in fixed-throughput applications by slowing the clock and lowering supply voltage instead of idling when computational workload varies. This can yield a typical power savings of 30–50%. If latency can be tolerated, bufferi...
متن کاملPerformance Characterization of the Low-Power Halo Electric Propulsion System
Performance measurements have been obtained of a novel propulsion concept called the Halo thruster under developmentwithin theUniversity of Surrey. TheHalo thruster, a type of cusped-field thrusterwith close similarity to the cylindrical Hall thruster, is motivated by the need for low-power and low-cost electric propulsion for the small satellite sector. Two versions of the device are investiga...
متن کاملLow Dielectric Materials for Microelectronics
Over the past half century, low dielectric materials have been intensively researched by ceramic and polymer scientists. However, these materials possess a vast myriad of electrical, thermal, chemical, and mechanical properties that are just as crucial as the name that classifies them. Therefore, in many cases, the applications of low dielectric constant materials are dictated by these other pr...
