A MoO3/Ag/MoO3 (MAM) transparent electrode was developed which aims for realizing transparent organic light-emitting diodes (TOLEDs) with different emission colors. The performance of the transparent electrode is significantly influenced by the thickness as well as the surface morphology of the silver film in MAM structure. The thermal evaporation process of the silver layer adopted varied deposition...
The paper presents a low temperature (with 60 °C) inkjet printing and filling process to realize low resistive Ag TSV (Through Substrate Vias) with the aspect ratio of via depth vs. diameter from 2 to 5 in a SU-8 substrate potential for flexible microsystem packaging applications. Combining humidity control and layer-by-layer Ag mirror reaction, the proposed process technology can accomplish a fully...
Unlike well accepted FPGA emulation for digital circuits, there is no winning emulation solution for analog and mixed-signal (AMS) circuits. This paper presents an analog circuit emulation based on wave digital filters (WDFs), which covers the entire flow of transforming an AMS circuit from SPICE netlist to hardware implementation in FPGA. More specifically, it presents the theoretical support of...
As the modern city arterial traffic, urban rail transit system has good effectiveness. It has regular starts and stops due to its specific operating conditions. A considerable amount of energy has been saved because kinetic energy can be recycled during braking and released when accelerating. This paper discussed the possibility of equipping the rail transit system with the hydraulic storage transmission...
Based on LabVIEW, the measurement system of I-V characteristics of solar energy is designed with a solar simulator, a Keithley 2400 Source Meter and a GPIB port. The system can quickly describe the I-V characteristic curves and calculate the basic characteristic parameters and focus on the analysis of the series resistance (Rs) and shunt resistance (Rsh). The results of the measurement demonstrate...
This work proposes process/resistance variation-insensitive read schemes for embedded RRAM to achieve fast read speeds with high yields. An embedded mega-bit scale (4Mb), single-level-cell (SLC) RRAM macro with sub-8ns read-write random access time is presented. Multi-level-cell (MLC) operation with 160ns write-verify operation is demonstrated.
We have designed an inductively coupled oxygen sensor suitable for operation at temperatures in the 500-1000 C range. A prototype sensor has been fabricated on alumina substrates using screen printing. The sensor consists of an RLC resonant circuit where the oxygen-sensitive ZnO resistor varies the quality factor. Changes in the quality factor are measured using an admittance bridge coupled to the...
This work demonstrates the first fabricated macro-level RRAM-based nonvolatile SRAM (nvSRAM) that use a new 8T2R (Rnv8T) cell to achieve fast NVM storage and low VDDmin read/write operations. The Rnv8T cell uses two fast-write low-current RRAM devices, 3D stacked over the 8T, to achieve low store energy with a compact cell area (1.6x that of a 6T cell). A 2T RRAM-switch provides both RRAM control...
Some of the components used in switch-mode power converters, such as inductors and transformers, may cause substantial power loss when switching frequency is largely increased. If extra heat dissipation or decreased efficiency is not acceptable, one needs to search for a method of reducing power loss. With higher switching frequency, inductors and transformers are commonly implemented with traces...
