An Enhanced PIN Diode Model for Voltage-Controlled PIN Diode Attenuator
33rd European Microwave Conference, 2003, 2003This paper presents an enhanced PIN diode model for the voltage-controlled PIN diode attenuator. The proposed model operates well when it is used in the voltage-controlled mode as well as current-controlled mode, and it is a simple and straightforward model, since the PN junction diode of this model has the same I-V curve as that of the PIN diode.

AIP Conference Proceedings, 2008
A review of the application of PIN diodes as radiation detectors in particle counting, X‐ and γ‐ray spectroscopy, medical applications and charged particle spectroscopy is presented. As a practical example of its usefulness, a PIN diode and a low noise preamplifier are included in a nuclear spectroscopy chain for X‐ray measurements.

Heterojunction PIN diode switch
IEEE MTT-S International Microwave Symposium Digest, 2003, 2003This paper describes the development of a heterojunction AlGaAs/GaAs PIN diode as a replacement for the homojunction GaAs PIN diodes commonly used in microwave systems as a control element for commercial and military switch applications up through millimeter wave frequencies. In particular, a single heterojunction PIN diode, when simulated at a bias of

2010 Second Pacific-Asia Conference on Circuits, Communications and System, 2010
In this paper, a multi-application PIN diode is presented. The PIN diode structure is similar to conventional PIN diodes, but only difference is that a layer is used in the middle of layers. The diode has 4 pins. Proportional to the applied voltage to the two control pins, it can be achieved a value arbitrary of series capacitance and resistance.

PIN silicon diode fast neutron detector
Radiation Protection Dosimetry, 2005Two batches of diodes, with different structural ratios (the ratio of area and thickness), were made using different manufacturing processes. The energy response of the first batch to 15 kinds of monoenergetic neutrons ranging from 180 keV to 17.56 MeV was tested, and the neutron source response of both batches to 239Pu-Be neutron source was measured ...
