Abstract

As the progress of technology continues in accordance to Moore’s law, the density and downsizing of circuitry presents a significant vulnerability to the effects of soft errors. This study proposed a novel method to mitigate soft errors by increasing the robustness of complementary metal oxide semiconductor (CMOS) technology against soft errors via the use of transmission gates within the memory nodes of static random access memory (SRAM) which functioned as a low pass filter that disallowed the occurrence of data corruption. The proposed SRAM was tested against parameter variation of supply voltage and temperature. The critical charge was observed to increase with supply voltage increase, with the opposite being true of the increase in temperature. The increase in critical charge of up to 88.63% was achieved with regards to parameter variation for the transmission gate SRAM in comparison to the 6T SRAM.

Abstract

In this work, a battery-integrated three-input converter is proposed. The topology combines a traditional boost converter on one side with a non-coupled inductor-based buffer stage on the other side. Some merits of the converter are a high voltage gain, a high output voltage in the battery discharging mode, and a wide range of output voltage. The bidirectional port makes it attractive for renewable energy (RE) sources like solar and fuel cells. The converter can operate in three modes that are determined by the availability of RE sources and the battery state of charge (SOC). The power management algorithm enabled the converter to work in either single-input, double-input, or three-input configurations. The duty ratios of assigned power switches controlled the output voltage and the battery charge/discharge. Steady-state analyses and dynamic modeling are presented and discussed. At 12 V and 24 V input voltage, the output voltage of 315.52 V was delivered in the battery-excluded mode. The battery discharging mode delivered 311.57 V while the battery charging mode delivered 301.32 V. The proposed converter can serve low to medium power voltage/power applications. The hardware experiments verify the workings of the proposed converter.
