Advanced Functional Materials, EarlyView.A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

Programmable Current‐Mode Universal Active Filters Employing Current Conveyors [PDF]
Active and Passive Electronic Components, 1998 Novel current‐mode active filter circuits using current‐conveyors are presented. The proposed circuits can realize all standard second‐order filter functions. The circuits enjoy high output impedances and can, therefore, be easily cascaded to produce higher order filters.

Temperature independent current conveyor precisionrectifier
Electronics Letters, 1994 A dual current conveyor based rectifier circuit with low temperature sensitivity is presented. The use of a DC current source to bias the rectifying diodes provides higher temperature stability than previously reported designs. In addition the output offset voltage is easily controlled and adjusted to a minimum low value. >

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
