Micro Faraday-Element Array Detector for Ion Mobility Spectroscopy
The novel ion mobility spectrometry (IMS) includes a drift tube having a collecting surface covering a collecting area at one end of the tube. The surface comprises a plurality of closely spaced conductive elements on a non-conductive substrate, each conductive element being electrically insulated from each other element. A plurality of capacitive transimpedance...

Differential Transimpedance Amplifier Circuit for Correlated Differential Amplification
Researchers at the University of Arizona have created a differential transimpedance amplifier circuit for correlated differential amplification. The amplifier circuit increases electronic signal-to-noise ratio in charge detection circuits designed for the detection of very small quantities of electrical charge and/or very weak electromagnetic waves....
