In this paper, the influence of metal particle position at insulating spacer on partial discharge (PD) characteristics is studied by using the ultra high frequency (UHF) detection method in a 252kV GIS PD experimental platform. The PD inception voltage (PDIV), phase resolved partial discharge (PRPD), phase resolved pulse sequence (PRPS) and UHF signal waveform and its frequency spectrum are investigated...
A high-performance bootstrap switch for low-voltage switched-capacitor (SC) circuits is presented. The switch enables the precise sampling of input signals on a low voltage supply with high speed, low nonlinear distortion. Experimental results in TSMC 130nm CMOS process show that a peak signal-to-noise-and-distortion ratio (SNDR) of 102.8 dB, spurious-free dynamic range (SFDR) of 104.6 dB and total...
