歐洲學校

歐洲學校

台灣人普遍都能念出美國五所以上的學校,

但是....

Imperial College London (United Kingdom)

Delft University of Technology (Netherlands)

ETH Zürich (Switzerland),

RWTH Aachen (Germany)

ParisTech (France)

請問上面學校你認識幾間?

包含鼎鼎大名的ETHZ, 愛因斯坦畢業的學校,

我很好奇台灣有多少人認識,

要想在台灣混吃, 沒事不要來歐洲的學校

因為沒人認識, 一點好處都沒有 XDDD

BTW, TUDelft 一年都上好幾篇 ISSCC, 好幾篇阿,

台灣一個學校要生一篇都很拼了

倫敦帝國理工, 巴黎高科, 這都是很牛的學校阿!!

上面五所學校組織一個聯盟叫做 IDEA

Demonstration

This is my second time for demonstrating my measurements in RWTH University.

The experts who came from Interdigital in USA asked some interesting questions about my work.

The demonstration is better than last time.

I think the experts and Prof. was discussing about some kinds of cooperations.

It was quite interesting experience for me.

After work, I google the company, Interdigital, and tune out they have stock on Nasdaq... OMG.

I should have asked their business cards. :)

Schade !!

The first demonstration was for Bosch GmbH. It's also a great company.

He Ain't Heavy, He's My Brother

他不重 他是我兄弟

這張是我近期的得意之作

點照片能看大張圖

我覺得這張照片的故事性很強, 有興趣的人可以自行體會

順便附上原唱

He Ain't Heavy, He's My Brother

Matlab

I should write something in my blog, otherwise people will forget my interesting space. :)

Recently, I am working on writing a script in Matlab to control instruments because of measuring my SMPA.

It is so fun. Guys in IAS group have lots experience about that.

It is easier for me to know how to start and how to drive an instrument.

I control a signal generator, spectrum analyzer, power supplies and so forth with Matlab.

My script is able to measure all data and then send me a EMAIL after finishing a measurement routine.

The chip has so many cases need to be measured. (up to 90k cases)

I can't image measuring the chip manually.

Thank Renato for giving me the tips.

I don't even need to stay in the measurement room. Instead, I just sit in my office and wait results.

LaTeX

About LaTeX

Recently, I start to use LaTeX to write a IEEE paper.

IEEE provides good templates for LaTeX.

Once you know how to use LaTeX to write it, you would not use Word anymore to do that. This is my view.

You don't need to care about where you should put figures and tables and don't need to deal with a reference list which BiBTeX will make automatically. (have to be set correctly first)

All you have to do is put the command "\cite{}" when you want to cite one paper. You don't need to bother with the formation of reference or correctly abb. of journals.

There are more advantages. The document file is very tiny and portable. You can choose whatever text editors. You can find LaTeX in any kinds of platforms such as MAC, UNIX and so forth. (some says even in Smart phones) You even can use a variable in a manuscript. The most important is you pay nothing including a reference management software. (I use JabRef).

For sure, there are drawbacks. One of the drawbacks for me is making a table. It is very tough to make a complex table. In the point of view, Word is better. Fortunately, I found the good tool called LaTable. Besides, how many tables you will have in a technical papers ?

I told my colleague the tool and asked him "have you used the tool" ? He answered "never, I don't need it"....

I should expect the answer because he is really an expert on LaTeX. He can make slides using LaTeX !!

What a weird guy....

White Christmas

White Christmas

屬於家人的日子

今年的德國下起十多年難得一見的大雪, 今天下班後, 同事約一起到Aachen的聖誕夜市喝熱紅酒, 他告訴我他印象中最深的 White Christmas是十幾年前的聖誕夜, 他跟父親還有哥哥一起在窗前喝酒, 看窗外飄著白雪, 聽起來好愜意.

今天的我也頗愜意, 早上在辦公室檢查了一下PA的Schematic, 意外發現為什麼會多吃電流, 找到問題出在哪裡, 馬上衝到實驗室驗證, 整個狀況都對了, 所有的現象都合理了. 我可以好好過聖誕了.

今天上班的時候廣播傳來這首歌, 之前還在Bonn的時候, 去參觀教堂時意外聽過現場版的, 當那個人唱完, 全部的人鴉雀無聲, 整個都被他的歌聲嚇傻, 頓時時光為了他而停頓, 那種清脆的吉他配上乾淨的聲音, 特別是教堂的共鳴與感覺都很好, 這種感覺只能親自體會.

祝我親愛的朋友們與家人, 大家聖誕快樂 !

在水管上找到, 跟大家分享,

何謂做研究?

何謂做研究?

錢

最近 TSMC 90 nm回來了, 所以開始用到RWTH的量測設備, 量到現在也過了快一個月, 感想就是做研究是用錢堆出來的.

比方說我這個量測需要180 deg balun, bias-tee, driver amplifier...etc, 他們採取的方式是花錢去買, 我當初跟老闆說 180 deg balun 不難, 我可以自己做, 他說直接買就好. 這有什麼好處勒?

省去很多很多 debug 的時間!! 買商規的器材可以排除很多不確定因素, 讓多數時間能專注在晶片的量測上面, 總之, 我的量測環境弄起來應該花超過3000歐.

什麼東西都還沒量到就先花3000歐 XD

1)大家晶片都差不多同一個時間回來, 而且都在趕 RFIC Deadline, 大家都想過個好聖誕節阿, 所以有五組人馬同時在量東西, 這很驚人, 大部分可以同步進行, 五套以上獨立的設備, 我真沒仔細數過有幾台NAs, 只知道有一台 Agilent 67 GHz 的 PNA-X, 跟 543 那台頻率一樣, 只不過這台是4 ports, 而且是 dual sources! 據說是3後面好幾個零歐.

2)實驗室大部分的的玩具都玩過了, 雕刻機, 打線機, 無塵室, 烤箱, Probe Station... 等, 德國這類的工具都很好, 精度高, 而且很方便, 各種奇怪的專用工具都有, 沒有的可以自己做*, 像他們可以自己焊 QFN 的包裝, 不是他們很厲害, 而是他們有很多奇怪的輔助工具, 光焊槍就有超過十種不同的頭, 解焊也一堆怪東西, 怪招很多.

3) 他們在趕工作的時候, 實驗室桌子也是非常亂的, 跟543一樣有的拼, 別被表面所唬了 XD

4) 我開啟了他們借儀器的先例... 借了一台據說整個德國只有兩部的儀器, 不過聽說樓下的都跑去 ETHZ量, 這該說天外有天? XD

* 他們有 machine shop 這種地方, 裡面有車床, 一切機械加工所要的設備, 最神奇的是這shop是屬於實驗室的, 也就是這些設備是歸屬於老闆的. 所以他們可以自己做一些很奇怪的夾具
