A TIA Is Used In A Receiver To Provide For Both High Speed And High Gain. However, There Is A Problem Faced When Developing A Receiver With TIA; Gain Peaking, Which Creates An Unstable Output. A Simple Approach Of Placing A Feedback Capacitor On The Amplifier Was Found To Reduce The Peaking From 2 Db Down To 0 Db.

Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to-substrate distance.

This optical fiber H sub (2) sensor was prepared by RF sputtering of WO sub (3) on the tip of the multimode fiber at 260 C and subsequently depositing a Pd catalytic layer. Highly uniform nanotextured film, with individual crystallites having diameters in the range of 35-50 nm was observed. The sensing mechanism was based on the reflectance change of Pd/WO sub (3) layers towards H sub ( ...

Subsequently, a catalytic palladium (Pd) layer was deposited onto MoO 3 layer by e-beam evaporation. Scanning electron microscopy (SEM) revealed MoO 3 nanorods grown in various directions and X-ray diffraction (XRD) confirmed the growth of orthorhombic MoO 3. Optical hydrogen (H 2) sensing performance of nanostructured Pd/MoO 3 films were investigated at a ...
