This article presents 3D-formed together with a narrow fabric-based interconnect system. study showcases methods materials for fabrication system,...
Sensitivity to supply voltage, temperature and process variations of a number current reference topologies novel circuit is compared in ON Semi I3T80 technology. The shows the lowest dependency, while dependency remain acceptably low.
This paper proposes an automated approach for the optimization of number active segments in switching DC-DC converters with a segmented power stage. The drain-source voltage MOSFET is used to estimate load current, and segment controller activates optimized segments. Using this automatically balances loss conduction converter over range. proposed concept implemented prototype discrete 500 kHz boost converter, which confirms efficiency Potential applications include high converters, where...
4-phase 2-branch and 16-phase 8-branch charge pumps are proposed to decrease the power dissipation due parasitic capacitance. By using recycling concept, efficiency is increased about 55% 88% respectively compared a traditional Dickson pump. The multi-branch can also significantly reduce output voltage ripple.
A new high-voltage driver, originally designed for an 800×600 passive matrix AFLC display application, is integrated in a 0.35μm CMOS technology. The IC features 65V driving capability on all 300 outputs and able of generating kinds complex waveforms that are constituted out 8 voltage levels (7 ground).
