Enclosure circulation of Gas Insulated Switchgear (GIS) and Very Fast Transient Overvoltage (VFTO) are harmful to many respects of power system, including system's security, stability and economic. The effective inhibition of GIS enclosure circulation and VFTO has attracted wide attention. In this paper, GIS enclosure circulation and transient ground potential has been modeled and analyzed. Firstly,...
As an ideal candidate for biology information detection, flexible resistance-array-type sensors have attracted extensive attention. But owing to the Neighbor Disturbance in resistance array, the accuracy of the sensors has been limited greatly. In the presented work, a novel resistance measuring circuit has been developed with equipotential shielding method, which shows a better accuracy in detecting...
This paper presents a series of scalable equivalent circuits using an analytical method describing the electromagnetic coupling in the lightly doped CMOS substrate and the isolation structures such as the implanted guard ring. Implemented in Grace Semiconductor Manufacturing Corporation (GSMC) generic 0.13-$\mu$m RF CMOS technology, the measurement and full-wave simulation are carried out to verify...
This paper presents a compact model for p-minus substrate guard ring (psub GR) combined with p-plus guard ring (p+ GR) in lightly doped CMOS substrates. The model can be used to predict the noise suppression performance of psub GR in terms of S-parameters, which is useful for substrate noise mitigation in mixed-signal system-on-chips. The efficiency of the model has been validated by full wave electromagnetic...
In this report, the bismuth triborate piezoelectric crystals,α-BiB3O6(BIBO), were investigated for potential sensor applications. The dielectric, piezoelectric and electromechanical properties were evaluated by using the impedance method, where the largest piezoelectric charge coefficients were found for d22, being on the order of 40.0pC/N, with corresponding piezoelectric voltage coefficients g22...
