A nonlinear LCR parallel circuit model of a single photon avalanche diode (SPAD) is derived from Lienard-type differential equation. The resistance and the inductance associated with multiplication (AM) are time-dependent governed by time constant due to impact ionization ratio. Time dependences current, voltage, resistance, in analyzed numerically solving During initial generation Geiger-mode ...

The results show that suitable choice v can lead an optimal effect best

The capacity of embedded memory on LSIs has kept increasing. It is important to reduce the leakage power of embedded memory for low-power LSIs. In fact, the ITRS predicts that the leakage power in embedded memory will account for 40% of all power consumption by 2024 [1]. A spin transfer torque magneto-resistance random access memory (STT-MRAM) is promising for use as non-volatile memory to redu...

This work presents a novel method to determine the parallel resistance of individual solar cells in an amorphous silicon based photovoltaic module. The method does not require accessing to the contacts of every cell. Therefore, it is suitable for measurements on encapsulated modules without disassembling and possibly damaging the module. The used setup measures only the current/voltage characte...

The presently used hollow fiber membrane modules consist of a bundle of fibers in a cylindrical polymer or metal shell parallel to the shell axis. The feed solution flows either through the lumen or at the outside parallel to the fibers. This paper compares the performance of these modules with a new transverse flow module where the hollow fibers are positioned perpendicularly to the flow direc...

Electrophysical study is given for signal transmission characteristics with the axon in neurons. Electrical analysis was done under voltage equilibrium and current continuity conditions. Inductance L and capacity C per unit length are obtained for lossless axon. Attenuation, phase rotation, and phase (signal) velocity are given for axon with loss. It is then presented that higher velocity and w...

The polarization resistance and capacitance of platinum black electrodes in contact with aqueous NaCl solutions was investigated. A series of measurements were made at 259/0.1 8C in the 10 Hz to 10 MHz range using a HP 4192A Impedance Analyzer. The measurement cell has flat parallel platinum electrodes 15 mm in diameter, with a continuously variable spacing from 0.5 to 9 mm. They were platinize...

The search for nonvolatile memory concepts has a massive impact on the development of nanoscopic systems with adjustable electrical properties. Capacitor-like structures composed of insulating materials sandwiched between metallic electrodes are envisioned to overcome the limitations associated with conventional charge storage devices and may open the road to neuromorphic computing. Together wi...
