GaInP/GaAs HBT inductorless wideband amplifiers using shunt-series shunt-shunt dual-feedback topology (Kukielka topology) and shunt-series series-shunt dual-feedback topology (Meyer topology) are demonstrated in this article. Three amounts of feedback are applied on each topology. At the high-gain mode, the Kukielka/Meyer wideband amplifier achieves the small-signal power gain of 30/27 dB with ...

Four circuit schemes that use partial positive feedback for gain enhancement in CMOS OTAs are examined. These circuit schemes are classiied as type I and type II circuits. Type I circuits use a diierential input pair with positive feedback and type II circuits use a active load with positive feedback. As the primary emphasis of these circuits is for micropower operation, the circuits have been ...

INTRODUCTION Successful control of multi-degree of freedom upper limb prostheses generally uses some form of sequential instruction. This is because simultaneous control of multiple inputs requires a considerable concentration to be operated effectively. In contrast, the natural arm is controlled in a parallel manner with a high level of subconscious control. Such control uses feedback, the per...

With traditional open-loop scheduling of network resources, the quality-of-control (QoC) of networked control systems (NCSs) may degrade significantly in the presence of limited bandwidth and variable workload. The goal of this work is to maximize the overall QoC of NCSs through dynamically allocating available network bandwidth. Based on codesign of control and scheduling, an integrated feedba...

In this research, we examine the problem of real-time video streaming over the Internet by introducing an adaptive least-mean-squares (LMS) bandwidth controller to adjust the amount of video data uploaded to the network so that the packet loss can be minimized in face of network congestion. The adaptive LMS bandwidth controller, which resides at the client end, sends a feedback signal to the se...

The problem of fair distribution of available bandwidth among traffic flows or aggregates remains an essential issue in computer networks. This paper introduces a novel approach, called the Exact Bandwidth Distribution Scheme (X-BDS), for dynamic and fair distribution of available bandwidth among individual flows. In this approach, the edge routers keep per-flow information, while the core rout...
