In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...
Abstract In the present work, improvement of Newton’s method with high order convergence has been suggested. This is based on Two-Point Bracketing method. The proposed Inverse Quadratic Interpolation requires two steps per iteration. By means numerical equation one diode model PV equivalent circuit, included five values R from 1 to 5 ohms (load resistance circuit). results obtained explain that...
Current microfluidic paper-based devices lack crucial components for fluid manipulation. We created a fluidic diode fabricated entirely on a single layer of paper to control the wicking of fluids. The fluidic diode is a two-terminal component that promotes or stops wicking along a paper channel. We further constructed a trigger and a delay valve based on the fluidic diode. Furthermore, we demon...
The Libbrecht-Hall circuit is a well-known, low-noise current driver for narrow-linewidth diode lasers. An important feature of the circuit is a current limit to protect the laser diode. As the current approaches the maximum limit, however, the noise in the laser current increases dramatically. This paper documents this behavior and explores simple circuit modifications to alleviate this issue.
New diode structures without the field-oxide boundary across the p/n junction for ESD protection are proposed. A NMOS (PMOS) is especially inserted into the diode structure to form the NMOS-bounded (PMOS-bounded) diode, which is used to block the field oxide isolation across the p/n junction in the diode structure. The proposed N(P)MOSbounded diodes can provide more efficient ESD protection to ...
Abstmct-The noise equivalent circuit of a semiconductor laser diode is derived from the rate equations including Langevin noise sources. This equivalent circuit allows a straightforward calculation of the noise and modulation characteristics of a laser diode combined with electronic components. The intrinsic junction voltage noise spectrum and the light intensity fluctuation of a current driven...
This paper describes 420GHz subharmonic mixer based on heterogeneous integrated schottky diode designed by University of Electronic Science and Technology of China (UESTC) and fabricated by China Electronics Technology Group Corporation-13 (CETC-13). The whole circuit including schottky diodes is integrated directly on the 50 μm quartz instead of the traditional 12 um GaAs substrate thus the ci...
In this paper, new simple circuit models for developed SiC pin diodes are proposed. They are based on the electrical characteristics obtained in experiments without any detail information of internal structure and physical parameters. The validity of the circuit models is confirmed by correspondence between simulated characteristics and experimental one. The model installed in the experimental ...
For the diode circuits shown in Figure 1, consider the diodes to be ideal. The input voltage vI given to the circuit is a sinusoid with a peak value of 6V and frequency 2kHz. For each circuit (a) Derive the expression for the transfer characteristic vO versus vI for the circuit. (b) Plot the transfer characteristic vO versus vI indicating the values of all significant points and the values of t...
