Summary: This paper investigates the measurement errors in multi-pixel thermopile sensors with networked arrangement through mathematical modeling and experimental study. The results indicate that the actual response voltage, resistance, and array size of adjacent pixels have an impact on the measurement error. The study also demonstrates that solving the actual response voltage of each pixel without introducing more equations is challenging.

Summary: In this article, an integrated gate driver is proposed to limit the peak negative gate voltage of SiC MOSFETs and provide reliable short-circuit protection. The crosstalk voltage suppression is achieved through a simple auxiliary branch and the negative peak voltage is eliminated by the high impedance gate driving loop. Furthermore, the auxiliary circuit is used for a two-step short-circuit protection by identifying the shoot-through current.

Summary: This article presents a method for evaluating the implications of threshold voltage (VTH) drift from gate voltage stress in SiC MOSFETs, which uses Miller coupling to characterize the impact of bias temperature instability (BTI)-induced VTH shift. Unlike traditional BTI characterization methods, this approach considers the actual converter environment to study the implications of VTH shift, making it more relevant for applications engineers. Studies on temperature, recovery time, and stress polarity have been conducted on commercially available SiC MOSFETs.

Summary: This article proposes a novel negative voltage self-recovery gate drive (NVSRGD) to suppress crosstalk in gallium nitride (GaN) based bridge configuration. By using a resistor-capacitor-diode voltage divider, a negative gate-source voltage is established to suppress positive crosstalk. In addition, an antiparallel diode is added to create a low-impedance Miller current path, working together with the self-recovery gate-source voltage to suppress negative crosstalk. The effectiveness of this method is verified through double-pulse testing based on GS66508B.

Summary: This paper proposes a solution to improve the reliability and reduce the cost of implementing flash memories. A pre-processing method is used to reduce the number of scanning voltage steps, reducing the time and energy consumption of multiple read operations. The proposed single state asynchronous estimation (SSAE) method is shown to reduce computational and space overhead compared to the two-state asynchronous estimation (TSAE) method, and it also reduces RBER without exact knowledge of noise.

Summary: CuSCN-based TFTs with solution-processed chitosan electrolyte are fabricated, demonstrating low operation voltage and high gate capacitance. The threshold voltage, on/off ratio, and field-effect mobility are characterized. The threshold voltage of CuSCN-based TFTs can be significantly changed by laser or annealing treatment. In addition, NAND logic function is implemented for the first time on CuSCN-based TFTs, opening up new possibilities for inorganic semiconductors and logic applications.
