A new electronically tunable phase shifter employing current-controlled current conveyors

Abstract: A new canonical current-mode (CM) filter topology is presented. It realizes first-order allpass filtering functions using two dual-output current-controlled current conveyors (DO-CCCII) and a single capacitor. The topology gives both inverting and non-inverting types of these filters. Owing to electronically tunability properties of the CCCII, phase response of the circuit can be controlled by an external control current. Realization of the allpass filter imposes no matching condition. All outputs of the filters exhibit high output impedances so that this property makes the circuits very attractive from the viewpoint of cascading in current mode. The theoretical results are verified with PSPICE simulations using a BJT realization of CCCII.

Which One Triggers the Other? Technological or Social Innovation

Abstract: The term innovation has sometimes been used as a synonym for technological innovation until the concept of social innovation attracted academic attention. Since then, these two types of innovation have been investigated individually. It can be claimed that, despite the great importance of social innovation studies, technological innovation studies received more attention. In addition, there are limited studies that have examined technological and social innovation together. The aim of this study was to examine the causal relationship between technological and social innovations. The impact of entrepreneurial characteristics on social innovation was also analyzed. This study was based on a comprehensive field study including 767 university students from 10 universities from different regions of Turkey. Regression analyses and structural equation modeling confirmed that social and technological innovation were related to one another, and both were correlated with a particular constellation of personal chara...
