Phased array technology has brought revolution not only in the defense but also in the commercial industry. Considering the development taking place in this area, it can be safely said that the future belongs to the phased array technology. This paper presents system level modeling and integration of the front end of phased array radar. This includes the modeling and simulation of an antenna array,...
Phased array radars have received considerable importance both in commercial and defense communications. Lot of research has been carried out regarding development of its necessary components such as the antenna array, transmit/receive module (TRM) and processor unit. The cost, efficiency, wide bandwidth, and fabrication technology for the TRM have been pursued as key research areas. Cost reduction...
In fields like medical science, communication, weather forecasting and defense industry, active phased array radars is a revolutionary development, due to its benefit of beam steering over conventional radar. Small size, light weight, efficient and high gain antenna array design are important areas of research in active phase array radar that can meet the subject requirements. Paper presents compact...
An integrated CMOS amperometric instrument with on-chip electrodes and packaging for biosensor arrays is presented. The mixed-signal integrated circuit supports a variety of electrochemical measurement techniques including linear sweep, constant potential, cyclic and pulse voltammetry. Implemented in CMOS, the chip dissipates 22.5 mW for a 200 kHz clock. The...
An integrated amperometric instrumentation system with on-chip electrodes for biosensor arrays is presented. The mixed-signal integrated circuit supports a variety of electrochemical measurement techniques including linear sweep, constant potential, cyclic and pulse voltammetry. Implemented in 0.5 μm CMOS, the 3×3 mm2 chip dissipates 22.5 mW for a 200 kHz clock. The highly programmable chip provides...
