Comparative Analysis of Noise Margin Between Pure SET-SET and Hybrid SET-PMOS Inverters

Chinese Journal of Electronics 2025年第1期34卷 146-155页

作者： Fan Zhang Yi Liu Yibo Wang Minghu Wu Sheng Hu Youli Dong Hubei Key Laboratory for High-Efficiency Utilization of Solar Energy and Operation Control of Energy Storage System Hubei University of Technology School of Electrical and Electronic Engineering Hubei University of Technology

Single-electron transistor（SET） is considered as one of the promising candidates for future electronic devices due to its advantages of low power consumption and high integration. The comparative analysis of SET-based inverters, especially the noise margin, is carried out. Pure SET-SET and hybrid SET with p type metal oxide semiconductor（SET-PMOS） inverters are designed for investigation. The effects of SET supply voltage, junction resistance and junction capacitance on noise tolerance and power consumption of inverters are studied. For hybrid SET-PMOS inverters, the noise margin for a logic high（NMH） is less than 60 mV under various conditions, which may become the bottleneck of its application. For pure SET-SET inverters, both NMH and the noise margin for a logic low（NML） could reach 300 mV at a supply voltage of 0.8 V. The minimum power consumption of pure SET-SET and hybrid SET-PMOS inverters is 2.85 nW and 58 nW, respectively. The pure SET-SET inverters have greater noise tolerance and lower power consumption, which is more conducive to large-scale integration. When junction capacitance CJ= 0.0273 aF and junction resistance RT≥1 MΩ in SET-SET inverters at a supply voltage of 0.8 V, the NMH and NML are not significantly affected by the junction resistance and the noise margin fluctuates at 300 mV.

The doubly-fed wind turbine based on grid forming control has the ability to establish terminal voltage independently and maintain stability, but the quantitative analysis of grid-connected stability and dynamic performance is insufficient, which affects the engineering application. To solve this problem, a small signal analysis model of grid forming controlled doubly-fed wind turbine is established. And based on the oscillation mode and participation factor analysis, this essay finds out the dominant modes which are influenced by grid forming control and key control parameters. Furthermore, based on the root locus analysis, the influence of grid strength and key control parameters on the stability and dynamic performance of the system is revealed as well as the variation law. Finally, the simulation model of the grid forming doubly-fed wind turbine is built in MATLAB/Simulink, and the simulation proves the accuracy and effectiveness of the theoretical analysis, which is expected to guide the popularization and application of the grid forming doubly-fed wind turbine. © 2023 IEEE.
