Reactive matching is extended to wide bandwidths using the impedance property of LC-ladder filters. In this paper, we present a systematic method to design wideband low-noise amplifiers. An SiGe amplifier with on-chip matching network spanning 3-10 GHz delivers 21-dB peak gain, 2.5-dB noise figure, and -1-dBm input IP3 at 5 GHz, with a 10-mA bias current.

Real-time path planning can efficiently relieve traffic congestion in urban scenarios. However, how to design an efficient path-planning algorithm to achieve a globally optimal vehicle-traffic control still remains a challenging problem, particularly when we take drivers' individual preferences into consideration. In this paper, we first establish a hybrid intelligent transportation system (ITS), i.e., a hybrid-VANET-enhanced ITS, which utilizes both vehicular ad hoc networks (VANETs) and cellular systems of the public transportation system to enable real-time communications among vehicles, roadside units (RSUs), and a vehicle-traffic server in an efficient way. Then, we propose a real-time path-planning algorithm, which not only improves the overall spatial utilization of a road network but reduces average vehicle travel cost for avoiding vehicles from getting stuck in congestion as well. A stochastic Lyapunov optimization technique is exploited to address the globally optimal path-planning problem. Finally, the transmission delay of the hybrid-VANET-enhanced ITS is evaluated in VISSIM to show the timeliness of the proposed communication framework. Moreover, system-level simulations conducted in Java demonstrate that the proposed path-planning algorithm outperforms the traditional distributed path planning in terms of balancing the spatial utilization and drivers' travel cost.

Real-Time Path Planning Based on Hybrid-VANET-Enhanced Transportation System

In transportation-based cyberphysical systems (TCPS), also known as intelligent transportation systems (ITS), to increase traffic efficiency, a number of dynamic route guidance schemes have been designed to assist drivers in determining optimal routes for their travels. To determine optimal routes, it is critical to effectively predict the traffic condition of roads along the guided routes based on real-time traffic information collected by vehicular networks to mitigate traffic congestion and improve traffic efficiency. In this paper, we propose a Dynamic En-route Decision real-time Route guidance (DEDR) scheme to effectively mitigate road congestion caused by the sudden increase of vehicles and to reduce travel time and fuel consumption. DEDR considers real-time traffic information generation and transmission by vehicular networks. Based on the shared traffic information, DEDR introduces the trust probability to predict traffic conditions and to dynamically, en route, determine alternative optimal routes. DEDR also considers multiple metrics to comprehensively assess traffic conditions so that drivers can determine the optimal route with a preference to these metrics during travel. DEDR considers effects of external factors (bad weather, incidents, etc.) on traffic conditions as well. Through a combination of extensive theoretical analysis and simulation experiments, our data show that DEDR can greatly increase traffic efficiency in terms of time efficiency, balancing efficiency, and fuel efficiency, in comparison with existing schemes.

A Real-Time En-Route Route Guidance Decision Scheme for Transportation-Based Cyberphysical Systems

Nowadays vehicular traffic is a major problem. Drivers choose the route that they believe will be the fastest; however traffic congestion can significantly change the duration of a trip. Providing real-time traffic information to drivers and navigation systems helps them to choose the best route. In this paper, a new scheme for acquiring real-time traffic information on inter urban routes which are based on an amalgamation of VANET networks with both inter-vehicle communication (IVC) and vehicle road-side device communication (VRC) and conventional systems, is proposed. An appropriate cost function and its parameters are defined. New parameters are proposed for the first time to route guidance problems using traffic information such as uncertainty.

Acquiring real time traffic information using VANET and dynamic route guidance

A high input impedance, low output impedance, highly linear CMOS buffer is very desirable in many analog CMOS circuits. Conventional buffers employ feedback which severely limits bandwidth and linearity at even medium range frequencies. A recent open loop buffer, although linear, suffers from large power supply voltage requirement. This makes it undesirable for low voltage deep submicron processes. Here going to basics leads us to a very simple and very linear buffer which shows more than 26 dB THD improvement over conventional designs.
