Precise navigation is a vital need for many modern vehicular applications. The global positioning system (GPS) cannot provide continuous navigation information in urban areas. The widely used inertial navigation system (INS) can provide full vehicle state at high rates. However, the accuracy diverges quickly in low cost microelectromechanical systems (MEMS)(More)
GPS (Global Positioning System) has become an integral part of a vehicle system which provides speed, time, direction etc besides the navigation data. Speed is one of the primary attributes of vehicle accident. Many lives could have been saved if emergency service could receive accident information timely. This paper proposes to detect an accident from the(More)
In radio frequency identification (RFID) systems, performance degradation of phase locked loops (PLLs) mainly occurs due to high phase noise of voltage-controlled oscillators (VCOs). This paper proposes a low power, low phase noise ring-VCO developed for 2.42 GHz operated active RFID transponders compatible with IEEE 802.11 b/g, Bluetooth, and Zigbee(More)
Modern Radio Frequency (RF) transceivers cannot be imagined without high-performance (Transmit/Receive) T/R switch. Available T/R switches suffer mainly due to the lack of good trade-off among the performance parameters, where high isolation and low insertion loss are very essential. In this study, a T/R switch with high isolation and low insertion loss(More)
The shift register is the heart of the current digital data storage system. Current trends of wireless device designs are to balance the power consumption, cost and portability of the device. The worldwide research is giving emphasize on increasing the amount of memory at minimum possible space to reduce the overall size of the devices now a days. This(More)
Vehicle navigation is a crucial requirement for many applications. Global Positioning System (GPS) can provide accurate navigation information. But the GPS performance degrades and even a complete outage may occur in urban areas due to line of sight problem. Inertial Navigation System (INS) can provide navigation information during a GPS outage. However,(More)
RFID is a worldwide attractive technology for reliable wireless communication system. Automatic gain control system of such devices is very important which is performed by Variable Gain Amplifier (VGA). In this paper, a class AB VGA, consisting of a linear transconductor amplifier and a linear transimpedance amplifier, is designed and simulated in CEDEC(More)
Silicon on Insulator (SOI) technology has become one of the most promising technologies in semiconductor fabrication industry for its numerous advantages. This study presents merits and demerits of different SOIs presented in literatures and a comparative study is done based on several design and performance issues for low power applications. From the study(More)
Low noise and low Power transimpedance amplifiers (TIA) are essential module for optical sensor based systems. But low power and low noise TIAs are still a challenge for the scientists despite of rapid advances in complementary metal oxide semiconductor (CMOS) technology. This paper proposes a three-stage nested miller compensated (NMC) based design of low(More)
Radar and radio cannot pickup the low flying aircraft due to the limitation of radar horizon, which severely poses flight hazards. As such, tracking of the low altitude aircraft in real-time is a dire need. Global Navigation Satellite System (GNSS) receiver can provide position from the satellites. On the other hand, Global System for Mobile Communications(More)
