Large‐area homogeneous and uniform perovskite films are key to the mass production of solar cells, especially flexible ones. Different from solution‐processed preparation, herein an all‐evaporation technique is developed for both hole‐transporting layer in modules. With two‐step strategy active‐layer design, large‐area prepared via evaporation first PbI 2 then CH 3 NH I. An 2,3,5,6‐tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane (F4TCNQ)‐doped 4,4′,4″‐tris( N ‐(aphthalene‐2‐yl)‐...
A capacitance-to-voltage converter (CVC) is proposed in this paper and applied to a readout circuit for micro-electro-mechanical system (MEMS) accelerometer improve the power efficiency. In traditional circuit, front-end CVC has operate at high sampling frequency resist thermal noise deterioration due large parasitic capacitance introduced by mechanical sensing element. Thus, back-end analog-to-digital (ADC) also avoid aliasing when output signal of CVC, which leads consumption. The average...
The temporally and spatially resolved optical emission spectrum of Hα a pulsed spark discharge in water was experimentally measured. electron densities, along the radial direction filament, for with conductivity 100 μS/cm were investigated. density filament found to be 1018/cm3 order magnitude. highest measured at primary stage it decreased time. distribution increased from center edge filament.
Summary This paper presents a low dropout regulator (LDO) with wide input voltage range and high power supply rejection (PSR) for Hall sensor front‐end circuits, which is fabricated 0.18 μm BCD process. A topology in closed‐loop charge pump biases the gate of two‐stage cascode NMOS pass transistors proposed to increase immunity electromagnetic interference (EMI) capability automotive applications. Furthermore, power‐down protection circuit maintain reliability system, novel implementation...
ABSTRACT This paper presents a novel angle track converter for sinusoidal encoders. These encoders provide electronic signals in which the position is encoded form. work aims to reduce complexity and enhance conversion speed of sinusoidal‐to‐angle demodulation system. Considering periodicity sine cosine (SCSs), full range evenly divided into eight segments determine coarse angle. According specific segment, SCSs are reshaped proceeding demodulation. Then fine derived from based on division...

Abstract Tight carbonate reservoirs are widely developed in Arabian Sea. The character of the reservoir indicates high heterogeneity, poor physical property and low productivity which would lead to Unit Technical Cost (UTC). Past drilling experiences show that thin sweet identification is very important for field development. In this study, a new method spots prediction tight carried out, successfully used horizontal wells design. Two main aspects spot were summarized based on study: 1) For...
