A wide range of industry and scientific applications require continuous measurement granular or liquid material levels. For environmental science, these include snow depth, water level, soil erosion measurements. The modern market offers many different sensors, some which can be used for measurements, but them are expensive not autonomous. Current models also propose difficulties in organizing scalable campaigns limit coverage large areas. example, common depth level sensors ultrasonic,...
The authors have developed a low noise, power charge sensitive amplifier and pulse shaping circuit. application is for double-sided germanium strip detector, nominally providing 50 independent spectroscopy channels. An array of these detectors would provide significant improvements in imaging, sensitivity space-based gamma-ray astronomy. key features electronics are very power, small footprint per channel. Performance the first circuit good agreement with simulations, /spl sim/205e noise rms...
A wide variety of applications require a hard X-ray or gamma ray detector which combine both good spatial resolution and energy resolution. Double-sided solid-state strip detectors provide this capability, We report on the development CMOS electronics designed for photon detection with detectors. These include low noise preamplifier, semi-gaussian shaping amplifier, discriminator, peak circuitry. All circuits are to operate at power. Circuits have been duplicated in NMOS PMOS polarities...
