Microwave characteristics of sol-gel based Ag-doped (Ba0.6Sr0.4)TiO3 thin films

Autor: Cheolbok Kim, Kyoung Tae Kim, Yong-Kyu Yoon, Dongsu Kim, David E. Senior

Publikováno v: Thin Solid Films. 565:172-178

Dielectric Ba0.6Sr0.4TiO3 (BST) thin films with a different concentration of Ag-dopant of 0.5, 1, 1.5, 2, 3, and 5 mol % have been prepared using an alkoxide-based sol-gel method on a Pt(111)/TiO 2/SiO2/Si substrate and their surface morphology and c

Structural, Optical And Electrical Characteristics Basrtiox Thin Films: Effect Of Deposition Pressure And Annealing

Autor: Turkan Bayrak, Cagla Ozgit-Akgun, Eda Goldenberg

Publikováno v: Journal of Non-Crystalline Solids

Among perovskite oxide materials, BaSrTiOx (BST) has attracted great attention due to its potential applications in oxide-based electronics. However, reliability and efficiency of BST thin films strongly depend on the precise knowledge of the film mi

High Input Impedance NMOS-based Phase Shifter with Minimum Number of Passive Elements

Autor: Shahram Minaei, Erkan Yuce

Publikováno v: Circuits, Systems, and Signal Processing

In this paper, a new voltage-mode (VM) first-order phase shifter (all-pass filter) employing only four NMOS transistors and minimum number of passive elements (i.e. one resistor and one capacitor) is proposed. The proposed VM phase shifter has high i
