[IEEE 2019 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP) - Bochum, Germany (2019.7.16-2019.7.18)] 2019 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP) - New approach for the simulation of bent and crumpled antennas on a flexible substrate
摘要： First-ever 28 nm embedded split-gate MONOS (SG-MONOS) ?ash macros have been developed to increase memory capacity embedded in micro controller units and to improve performance over wide junction temperature range from C to 170 C as demanded strongly in automotive uses. Much attention has been paid to the degradation of the reliability characteristics along with the process shrinkage. Temperature-adjusted word-line overdrive scheme improves random read access frequency by 15% and realizes both of 6.4 GB/s read throughput by 200 MHz no-wait random access of code ?ash macros and more than ten times longer TDDB lifetime of WL drivers. Temperature-adaptive step pulse erase control (TASPEC) improves the TDDB lifetime of dielectric ?lms between metal interconnect layers by three times. TASPEC is particularly useful for a data ?ash macro with one million rewrite cycles. Source-side injection (SSI) program with negative back-bias voltage achieves 63% reduction of program pulse time and, consequently, realizes 2.0 MB/s write throughput of code ?ash macros. A spread spectrum clock generation and a clock phase shift technique are introduced for charge pump clock generation in order to suppress EMI noise due to high write throughput of code ?ash macros, and peak power of EMI noise is reduced by 19 dB.

Flat concentrator photovoltaic system for automotive applications
摘要： In this paper, we present a novel design and an optical simulation of a ?at concentrator photovoltaic (CPV) system for electric vehicle application. The sunlight concentration component is comprised of a planar waveguide integrated dichroic mirror-coated cone prisms and a mirror-coated lens array. Sunlight re?ects ?rstly at the mirror-coated lens array and then strikes the cone prism of the planar waveguide. The prisms are coated by the dichroic mirrors to divide the solar spectrum into two bands. The low-energy band is transmitted and reaches the GaInAsP/GaInAs dual-junction solar cells. The mid-energy band is re?ected at the prism surface and coupled inside the waveguide. The exit port of the waveguide is attached with GaInP/GaAs dual-junction solar cells. The simulation results demonstrated a maximum electricity conversion e?ciency of 32.88% at the high con- centration ratio. The system thickness is 35 mm, which is as thin as the conventional ?at photovoltaic panel and system allow for a lateral sun-tracking mechanism. This is suitable for installation on the vehicle's roof. The results showed that the presented ?at CPV system is a new approach for a highly e?cient application of solar energy to the electrical vehicle.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - A novel single layer dual linear polarization band-pass frequency selective surface for automotive fully coated glass
摘要： A single layer dual linear polarization Frequency Selective Surface (FSS) for automotive fully coated glass is presented. It acts as a band-pass ?lter for signals in the range of 640MHz to 3.3GHz. The performance of the proposed FSS element is assessed using CST Microwave Studio R(cid:2). Simulations show less than 10dB of attenuation all over the frequency band for an angle of incidence up to 70? in both polarizations. This promising result makes from the proposed FSS a good candidate to overcome the problem of connectivity of a handled device inside the vehicle to the mobile network.
