This paper describes the design of a 48 kJ/s high-voltage capacitor charging power supply (CCPS), focusing on its efficiency, power density, and reliability. On the basis of a series-parallel resonant converter (SPRC) that provides high efficiency and high power density owing to its soft-switching, the design of the CCPS is explained in detail, including its input filter, resonant tank parameters,...
Reliability data is presented for a 4Mb Ferroelectric Random Access Memory (F-RAM) embedded within a 130nm CMOS process. Write/read endurance in the device exhibits stable intrinsic bit properties through 2.7x1013 cycles. Data retention demonstrates 10 year, 85??C operating life. No fails were observed with full-chip endurance test to 108 cycles followed by 1,000 hours of data retention bake at 125??C...
ldquoTrenchrdquo capacitors containing multiple metal-insulator-metal (MIM) layer stacks are realized by atomic-layer deposition (ALD), yielding an ultrahigh capacitance density of 440 at a breakdown voltage VDB > 6 V. This capacitance density on silicon is at least 10times higher than the values reported by other research groups. On a silicon substrate containing high-aspect-ratio macropore arrays,...
The present paper investigates a novel type of voltage-clamped VVVF high-frequency power inverter comprising fast-switching SCR's and GTO's (or Power Transistors; PTR's) which provides power regenerating and voltage-clamped effects, and its useful modified circuit versions. The state-of-the art high-frequency inverter circuits proposed herein operate stably and efficiently in the frequency range of...
