Design of precision successive approximation ADC reference voltage source

“The overall accuracy of a high-resolution, successive-approximation ADC depends on the accuracy, stability, and drive capability of its reference. The switched capacitors at the ADC reference input are dynamically loaded, so the reference circuit must be able to handle currents that are time and throughput rate dependent. Some ADCs have… Continue reading

MAXIM’s Li-ion ModelGauge IC Solution

MAXIM has introduced ICs using ModelGauge, an advanced lithium-ion battery modeling algorithm, that continuously tracks a battery’s relative state of charge (SOC) over a wide range of charge/discharge conditions. The ModelGauge algorithm eliminates the current sense resistor and battery learning cycle required by other fuel gauges. Using the system’s microcontroller,… Continue reading

GAA FETs will pave the way for 2nm, 3nm development

“Some foundries are still developing new processes based on next-generation gate-all-around transistors, including more advanced high-mobility versions, but bringing these technologies into production will be difficult and expensive. Intel, Samsung, TSMC and others are laying the groundwork for a transition from today’s FinFET transistors to new gate-all-gate field-effect transistors (GAA… Continue reading

New research on high-performance lithium-sulfur batteries: carbon nanospheres can improve charge-discharge cycle stability

Currently widely used lithium-ion batteries can achieve an energy density of 265 Wh/kg and a capacity of 185 mAh/g, while lithium-sulfur batteries theoretically have an energy density of 2,600 Wh/kg and a capacity of 1,675 mAh/g . In other words, the performance of lithium-sulfur batteries is 10 times better than… Continue reading
