    40-48 GHz sub-harmonic transceiver for high data-rate communication system applications
    (2008-04-24) Jeng-Han Tsai; To-Po Wang; Kun-You Lin; Tian-Wei Huang; Yi-Cheng Lin; Hsin-Chia Lu; Huei Wang
    A 40-48 GHz sub-harmonic transceiver module for millimeter-wave (MMW) high data-rate communication systems has been developed in this paper. The highlights are a sub-harmonic transmitter with 12 plusmn 3 dB conversion gain, a power amplifier with 17 plusmn 2 dBm output power, a low noise amplifier with 5 plusmn 1.5 dB noise figure, and a sub-harmonic mixer with 15 plusmn 3 dB conversion loss from 40 to 48 GHz. Furthermore, two kinds of MMW high data-rate communication applications using the 40-48 GHz sub-harmonic transceiver module were demonstrated. The experimental results show that the 40-48 GHz transceiver has Gigabit transmission capability.

    MMICs in the millimeter-wave regime
    (IEEE Microwave Theory and Techniques Society, 2009-02-01) Huei Wang; Kun-You Lin; Zuo-Min Tsai; Liang-Hung Lu; Hsin-Chia Lu; Chi-Hsueh Wang; Jeng-Han Tsai; Tian-Wei Huang; Yi-Cheng Lin
    On the basis of the current status of silicon based MMICs, it is possible to implement millimeter-wave SOC in silicon-based technologies that include the antenna, a medium-power amplifier, a transceiver, an LO (frequency synthesizer), and baseband circuits in a single chip. With certain interconnection schemes, such as flip-chip, to connect the chip to the substrate, it is also possible to integrate the best possible chips for a millimeter-wave communication system. Currently, CMOS is the best choice for the baseband circuits, while GaAs and InP MMICs can provide the best noise/power performance in the transceiver. High-efficiency antennas can be implemented directly on the packaging substrate. The SIP approach has the optimal combinations of the components for the best performance in a particular system. For example, a system in a package including CMOS baseband circuits, GaAs/InP-based transceiver, high-efficiency antenna, and high-power amplifier can achieve the best system characteristics. As we have discussed, the scope of SOC can be expanded along with more advanced MMIC fabrication technology and design techniques.

    後悔與生活適應：自我關愛及自我批評之雙路徑中介效果檢驗
    (國立臺灣師範大學教育心理學系, 2016-09-??) 鄭怡; 林以正; Yi Cheng; Yi-Cheng Lin
    過去關於後悔的研究，大多針對後悔事件的類型進行分析，或探討個體的認知特性，來解釋後悔的發生率以及如何影響正負向的適應結果。但是作者認為這些文獻忽略了個體在後悔情緒中，往往也經歷著一個自我對話的過程：個體會審視著自己所做的行為及這些行為所帶來的後果，或者反省，或者耽溺，或者勉勵，或者責備。在這樣的對話過程中，個體與自己對話著的自我究竟要以什麼樣的態度，又與自己形成怎樣的關連，這種對話的方式應該是影響適應很重要的關鍵因素。本研究嘗試以不同的自我關愛因素來描述前述自我對話的過程，並假設其為後悔與適應之間的中介因素。研究結果顯示，個體在面對後悔事件時，省思之所以能夠帶來良好的適應狀況，是以自我關愛為中介歷程；另一方面，反芻則是透過自我批評使個體困於後悔情緒進而影響生活適應。作者同時也延伸討論自我關愛在個體面對負向事件時自我整合所可能扮演的角色。

    從情緒平和與止觀探討心理位移日記書寫方法的療癒機制
    (國立臺灣師範大學教育心理學系, 2013-03-??) 張仁和; 黃金蘭; 林以正; Jen-Ho Chang; Chin-Lan Huang; Yi-Cheng Lin
    以往心理位移書寫的研究主要聚焦於療癒效果跟位格特性的檢驗，探討其療癒效果機制的實徵研究仍付之闕如。本研究回顧相關文獻，並從情緒平和與心理學中的止觀概念切入探討其心理機制。本研究招募65名受試者，進行兩週共四次的心理位移書寫。結果顯示心理位移書寫能促進個體的情緒平和，並增加止觀程度，與心理適應指標的提升。多元迴歸分析也發現，藉由心理位移書寫所提升的止觀改變量，能有效預測個體心理適應指標的改變量。此結果支持心理位移藉由止觀的提升，促進心理適應的主張。文末針對心理位移書寫與止觀進行理論延伸與應用的討論。

    鈷及鐵薄膜於鎢(111)表面上的結構與磁性
    (2011) 林奕成; Yi-Cheng Lin
    在本篇報告中我們於100K的溫度將鈷或鐵蒸鍍在鎢(111)的表面並升溫至室溫後，藉著低能量電子繞射以及磁光柯爾效應探討其結構與磁性，此外我們將呈現樣品熱處理過程中所觀察到的特殊磁現象。
