A new technique for bandwidth enhancement of amplifiers is developed. Adding several passive networks, which can be designed independently, enables the control of transfer function and frequency response behavior. Parasitic capacitances of cascaded gain stages are isolated from each other and absorbed into passive networks. A simplified design procedure, using well-known filter component values...

This paper presents a model and theory for streaming layered video. We model the bandwidth available to the streaming application as a stochastic process whose statistical characteristics are unknown a priori. The random bandwidth models short term variations due to congestion control (such as TCP-friendly conformance). We suppose that the video has been encoded into a base and an enhancement l...

We report the optical injection modulation of semiconductor lasers by intra-cavity stimulated Raman scattering. This mechanism manifests itself as sharply enhanced modulation bandwidth in InAs/InGaAlAs/InP quantum-dash lasers when the injected photons are 33 +/- 3 meV more energetic than the lasing photons. Raman scattering measurements on the quantum-dash structure and rate equation models str...

A novel bandwidth enhancement design of planar Fshaped dipole antenna for RFID tag is proposed. With the use of two parasitic strips inset along the closed loop of the input IC chip in this proposed tag antenna, a new resonant mode close to 900 MHz band is excited to enhance the operating bandwidth. The obtained impedance bandwidth across the operating band can reach about 104 MHz for UHF band....

This paper gives a comparative analysis of an inductorless Complementary Metal Oxide Semiconductor (CMOS) Single-ended current-mode Transimpedance Amplifier (TIA) intended for use in front-end Optical communication for wideband operation. This technique uses N similar TIAs in parallel configuration to boost the overall bandwidth as well as the transimpedance gain which is not possible with volt...

The impedance bandwidth, one of the important characteristics of microstrip patch antennas, can be significantly improved by using a multilayer dielectric configuration. In this paper the focus is on bandwidth enhancement technique of a multilayer patch antenna for X-band applications. In order to enhance the bandwidth, antenna losses are contained by controlling those quality factors which can...

Reusing data in cache is critical to achieving high performance on modern machines, because it reduces the impact of the latency and bandwidth limitations of direct memory access. To date, most studies of software memory hierarchy management have focused on the latency problem in loops. However, today’s machines are increasingly limited by the insufficient memory bandwidth— latency-oriented tec...

A number of techniques can be used to eliminate reflections when the characteristic impedance of the line and the load impedance are mismatched. Impedance matching techniques can be designed to be effective for a specific frequency of operation (narrow band techniques) or for a given frequency spectrum (broadband techniques). The purpose of this paper is to make a comparative study on bandwidth...

This paper presents the bandwidth and gain enhancement of microstrip patch antenna using EBG for X band (10 Ghz) application. The surface waves must be suppressed to increase the bandwidth and gain by using EBG. By using EBG the stop band characteristics is created over certain frequency and that has been adapted to suppress the surface wave and to enhance the gain and bandwidth of the antenna ...

A stacked type stair-case patch antenna with dielectric substrate (εr= 2.33) has been conceived and is theoretically demonstrated. Unlike conventional microstrip antenna it shows remarkable improvement in bandwidth (around 20%) as well as gain (around 10.5 dBi). The proposed structure is designed with two identical stair-case patches. Thorough investigations of the proposed antenna along with t...
