Sizing nickel iron batteries for RAPS systems
Nickel-iron batteries have long life expectancy and are ::: tolerant of abuse or poor charge regimes. However their ::: larger internal impedance often results in premature voltage ::: cut-out with remote area power supplies (RAPS) inverters. A ::: new method for sizing nickel iron batteries is proposed, which incorporates a technique that helps address this problem at the design stage. An economic analysis is presented which reveals that nickel-iron batteries can represent a cost effective solution in some RAPS applications.
We study the Radiation-Induced Mismatch Enhancement (RIME) in 65 nm CMOS SRAM block designed for space applications. X-ray and heavy ion irradiation increase the number of non-rewriting cells.
