沿革

科技與工程學院（原名為科技學院）於87學年度成立，其目標除致力於科技與工程教育師資培育外，亦積極培育與科技產業有關之工程及管理專業人才。學院成立之初在原有之工業教育學系、工業科技教育學系、圖文傳播學系等三系下，自91學年度增設「機電科技研究所」，該所於93學年度起設立學士班並更名為「機電科技學系」。本學院於93學年度亦增設「應用電子科技研究所」，並於96學年度合併工教系電機電子組成立「應用電子科技學系」。此外，「工業科技教育學系」於98學年度更名為「科技應用與人力資源發展學系」朝向培育科技產業之人力資源專才。之後，本院為配合本校轉型之規劃，增加學生於科技與工程產業職場的競爭，本院之「機電科技學系」與「應用電子科技學系」逐漸朝工程技術發展，兩系並於103學年度起分別更名為「機電工程學系」及「電機工程學系」。同年，本學院名稱亦由原「科技學院」更名為「科技與工程學院」。至此，本院發展之重點涵蓋教育（技職教育/科技教育/工程教育）、科技及工程等三大領域，並定位為以技術為本位之應用型學院。

107學年度，為配合本校轉型規劃，「光電科技研究所」由原隸屬於理學院改為隸屬本（科技與工程）學院，另增設2學程，分別為「車輛與能源工程學士學位學程」及「光電工程學士學位學程」。

    A 30-100-GHz wideband sub-harmonic active mixer in 90-nm CMOS technology
    (IEEE Microwave Theory and Techniques Society, 2008-08-01) Jeng-Han Tsai; Hong-Yuan Yang; Tian-Wei Huang; Huei Wang
    This letter presents a 30-100 GHz wideband and compact fully integrated sub-harmonic Gilbert-cell mixer using 90 nm standard CMOS technology. The sub-harmonic pumped scheme with advantages of high port isolation and low local oscillation frequency operation is selected in millimeter-wave mixer design. A distributed transconductance stage and a high impedance compensation line are introduced to achieve the flatness of conversion gain over broad bandwidth. The CMOS sub-harmonic Gilbert-cell mixer exhibits -1.5 plusmn 1.5 dB measured conversion gain from 30 to 100 GHz with a compact chip size of 0.35 mm2. The OP1 dB of the mixer is -10.4 dBm and -9.6 dBm at 77 and 94 GHz, respectively. To the best of our knowledge, the monolithic microwave integrated circuit is the first CMOS Gilbert-cell mixer operating up to 100 GHz.

    Design and analysis of a 0.8-77.5-GHz ultra-broadband distributed drain mixer using 0.13-μm CMOS technology
    (IEEE Microwave Theory and Techniques Society, 2009-03-01) Hong-Yuan Yang; Jeng-Han Tsai; Chi-Hsueh Wang; Chin-Shen Lin; Wei-Heng Lin; Kun-You Lin; Tian-Wei Huang; Huei Wang
    A compact and broadband 0.8-77.5-GHz passive distributed drain mixer using standard 0.13-mum CMOS technology is presented in this paper. To extend the operation bandwidth, a uniform distributed topology is utilized for wideband matching. This paper also analyzes the device size and number of stages for the bandwidth of the CMOS distributed drain mixer. To optimize the conversion gain performance of the CMOS drain mixer, a gate bias optimization method is proposed and successfully implemented in the mixer design. This mixer consumes zero dc power and exhibits a measured conversion loss of 5.5 plusmn1 dB from 0.8 to 77.5 GHz with a compact size of 0.67 0.58 mm2 . The output 1-dB compression point is -8.5 dBm at 20 GHz. To best of our knowledge, this monolithic microwave integrated circuit has the widest operation bandwidth among CMOS wideband mixers to date with good conversion efficiency and zero dc power consumption.

    A 60-GHz CMOS power amplifier with built-in pre-distortion linearizer
    (Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01) Jeng-Han Tsai; Chung-Han Wu; Hong-Yuan Yang; Tian-Wei Huang
    A built-in pre-distortion linearizer using cold-mode MOSFET with forward body bias is presented for 60 GHz CMOS PA linearization on 90 nm CMOS LP process. The power ampli- fier (PA) achieves a of 10.72 dBm and of 7.3 dBm from 1.2 V supply. After linearization, the has been doubled from 7.3 to 10.2 dBm and the operating PAE at consequently improves from 5.4% to 10.8%. The optimum improvement of the IMD3 is 25 dB.
