A new switched-opamp technique is proposed to operate switched-capacitor circuits at supply voltages as low as 1-V without on-chip voltage multiplier or low-Vt devices. The main idea of the new switched-opamp technique is to implement an additional switchable operational amplifier (opamp) in parall.....

The present invention relates to a new method for the synthesis of triaroylbenzene by secondary amine and DMF-catalyzed cyclotrimerization of acetylenes. This method can be applied for the synthesis of new branched organic materials and polymers containing the triaroylbenzene moieties. The polymeriz.....

Conventional graphite made from sulfuric acid-graphite intercalation compound (GIC) contains much amount of sulfur, which cause environmental pollution and corrosion.The invention provides a new formic acid-GIC synthesized by an electrochemical process in which formic acid is used as electrolyte. Th.....

Electroplating-based flip chip solder preparation process had been widely used over other preparation methods. Although it is cheaper and is able to achieve the material deposition on the fine pitch I/O pads, the solder bumps resulted are not uniform and not quality-guaranteed. In this invention, ma.....

This improved material relates to novel planar materials having band gap properties, and in particular to such materials formed with fractal patterns. Band gap materials are ideal for shielding electromagnetic (EM) radiation as they have a gap in the transmission band thus blocking transmission of E.....
