We demonstrate high-speed charge detection at room temperature with single-electron resolution by using a radio-frequency field-effect transistor (RF-FET). The RF-FET combines a nanometerscale silicon FET with an impedance-matching circuit composed of an inductor and capacitor. Driving the RF-FET with a carrier signal at its resonance frequency, small signals at the transistor’s gate modulate t...

The nal upgrade of the DELPHI Silicon Tracker, to enable DELPHI to meet the physics requirements of LEP2, was completed in 1997. The tracker contains 888 detecting elements having a total active surface of about 1.6 m 2 of silicon, has 1399808 readout channels and covers polar angles between 11 and 169. It consists of: the Silicon Barrel, extending from 21 to 159 and playing the role of vertex ...

Abstract: Analog sampling systems based on switched capacitor techniques offer performance superior to that of flash A/D converters with respect to cost, density, dynamic range, sampling speed, and power consumption. This paper proposes a 500 MHz switched capacitor analog waveform sampling circuit for the camera electronics of the Cherenkov telescope. An experimental 4 channel analog memory wit...

Atypical white-matter integrity and elevated dopamine levels have been reported for individuals who stutter. We investigated how such abnormalities may lead to speech dysfluencies due to their effects on a syllable-sequencing circuit that consists of basal ganglia (BG), thalamus, and left ventral premotor cortex (vPMC). "Neurally impaired" versions of the neurocomputational speech production mo...

The operating principles and experimental results for the Army Research Laboratory's (ARL's) patented chirped amplitude modulation (AM) ladar using linear response detectors have been presented and published previously, and will be briefly summarized here (Stann, et. al., 1996). In ARL's current prototypes using unity gain detectors, amplifier noise limits the receiver sensitivity. This noise i...

Hybrid infrared focal plane arrays (IRFPAs) are more and more used in both infrared medium and long wavebands for many different applications. In order to offer more spatial resolution, larger format (2048×2048) start to be available, yet its final yield is so low that its cost is very high, and is not affordable. In this paper, basing on viscoplastic Anand’s model, the structural stress of ind...

The integration of the VMM3a Application-Specific Integrated Circuit (ASIC) into RD51’s Scalable Readout System (SRS) provides a versatile tool for readout Micro-Pattern Gaseous Detectors (MPGDs). With its self-triggered high-rate readout, analogue part that allows to get information on deposited energy in detector, and so-called neighbouring-logic recover charge distribution, this new system h...

The square checkerboard buckling deformation appearing in indium antimonide infrared focal-plane arrays (InSb IRFPAs) subjected to the thermal shock tests, results in the fracturing of the InSb chip, which restricts its final yield. In light of the proposed three-dimensional modeling, we proposed the method of thinning a silicon readout integrated circuit (ROIC) to level the uneven top surface ...
