小弟刚收到ucsb,ece的Communications and Signal Processing,control的ad,很奇
怪,自己现在做的是器件方面的,存储器和铁电材料什么的。对这个很不了解。
想问下1.UCSB的这个方向强吗?出来好找工作吗?
2.还想套下磁,问下这种方向能和器件工艺材料扯上吗?
3.最好能有人推荐个老师,
谢谢。

我们有个FR-103XL autocorrelator。Femtosecond fiber laser 连接这个
autocorrelator,autocorrelator有个PMT探测器,它的输出接示波器,进而观察
autocorrelation signal,不知道买个什么样的示波器(多少带宽和采样频率)就够用
了?谢谢
超短脉冲信息如下:
center wavelength: 1550nm
Repetition rate: 40MHz
Pulse width: 100 Fs

Try to stay beyond control. It is very hard to study and difficult to find a
job. Communication and signal processing are much better than control.

一段话概括“PCB design criteria for analog, RF, and mix-signal component
designs”是什么了?
proper grounding, shielding, 诸如此类的???有经验的大虾说说~~~

我两个都想知道,老板说我的方向是"compressive sensing"
是属于 “general statistical signal processing”

我现在有个问题请教大家 用Synthesis tool产生的GDS和自己做的Analog circuit 放
在一起 不能做LVS 只能手动检查 据说cadence有Mixed signal的flow 不知道具体是如
何的 ?

small signal analysis 的input一般不都是用AC source么?magnitude设为1就行了,
管他什么方波还是正弦波。

If we want to design a RF module (transceiver), do we have to use ADC?
Is there some method to directly send digtal signal?
Thanks a lot

还是自己回答算了。现在找到的一个关键词是 is not unique。
用google找"signal flow graph" "is not unique" 还找到一点相关的东西。

I think it's variable.
The reason is
A variable changes instantaneously when the variable assignment is executed.
On the other hand, a signal changes a delay after the assignment expression
is evaluated
correct?

我的毕业课题方向还没有定下来,正在跟老师讨论。
他给了我几个题目
• High voltage packaging for SMART GRID Applications
• Simulate, design and fabricate a high temp gate driver for SiC JFets
/MosFets
• ‘Optimal Designer’ of autonomous, alternative-energy supplied
systems
• Electromagnetic modeling of energy interconnects
• High Temperature operation of heavily doped silicon devices
我自己比较感兴趣的是电源管理。
我的目标是找工作,想利用这个毕业设计做个让自己好找工作的项目。
不拘于以上的东西,老师让我慢慢想,请教下各位有关Analog/Mixed Signal/Power
Electronics的比较热的方向或者说

What means the enable signal?
Can desertvalley explain this in more detail? I am very interested in this
topic, thanks!
h****n

I think if this enable signal is only valid for the current F/F, the delay
of the clock enable may result in hold-time violation of current F/F. At the
same time, it may also bring set-up time violation for successive F/Fs.
Am I right?

Your question sounds not clear to me.
Are you talking about defining delay constraints for CLK signals for
synthesis or CLK gating designs?

来自主题: EE版 - 做signal integrity的请进
signal integrity去做cable,connector的公司好像比较保险,记得去molex参观过,
用几台服务器run HFSS,hehe。
另外,一般的大芯片公司好像也有招的,不过和作天线,电磁干扰诸如此类的在一个组
,好像。

版上的那些朋友是正在工作的,做analog/mixed signal, 具体一点就是PMIC,DCDC。
做任何大系统和小电路的。请给我发站内信。我正在找intern,希望得到你的帮助。

本人以前从事的是power ic design,最近突然觉得高速高精度ADC之类的很牛逼,很需
要技术,也能卖钱。所以我想改行自学 mixed signal.
请问大家, 如果从头学起,有什么捷径没有啊,感觉要看的书太多了。。rf, analog,
digital, descreet time analysis, control theory...
欢迎板上的各位牛人参与讨论!

With a background in EE(DSP), I have been working as a firmware engineer in
a semiconductor company. My work involves both coding and algorithm
development. I am wondering if I should spend more time on algorithm side
doing more research work on signal/image area , or focus on CS stuff to keep
work as a 'programmer'.
Any suggestion?
h*******o

I recommend you can keep on the CS track. There are much more opportunities
on Firmware engineer (algorithm design, assembly coding, embedded system,
etc) instead of on signal/image research work.

keep

Come to image/signal side. You can get a postdoc position and certainly meet
your curiosity.

analog IC design就是模拟集成电路设计。。。
mixed-signal就是又有数字信号又有模拟信号。

Hi guys, we are a fast-growing start-up in Silicon Valley developing cutting
-edge SerDes technology; currently we have multiple job openings in high-
speed analog/mixed-signal design (wireline transceiver, PLL) at all
experience levels. Please contact me at h***********[email protected] if
interested.
Thanks!

我的background大致如此:
1.国内有过Analog(2年)和Mixed signal(1年)共3年的IC TEST 的经验。
2.有美国还不错的一所大学的EE的master。
3.最近刚绿卡,所以不需要sponsorship。
希望有非contract的IC test的职位,或者semiconductor行业相关职位都可。如果有对
我的背景感兴趣的,可以站内我你的job description,我可以发我的详细简历过去。
万分感谢!!

Hi,
Our group works on analog front end (AFE)and we have multiple openings for
senior level analog/mixed signal IC design engineer (no fresh college grad
at this point, sorry)
Pls message me txt format resume if interested. it doesn't have to include
much personal info. if you prefer to keep it private, but pls don't bluff as
that'll waste quite some time for everyone. I'll do light screen and ask
for a formal resume for my manager if there's a match.
We're a small company located in southern Ca... 阅读全帖

boss prefers referral so the position is not on company website and i don't
have a job description. Our group (mixed signal) works on analog front end,
we design VGA, ADC, DAC, PLL, references circuits etc.

本人university of michigan的MS,学的是analog/ADC方向,GPA不错,除了做过几个
大的course project以外,暑假跟着prof. Michael Flynn做了一个delta sigma ADC的
chip tape out。希望qualcomm的前辈可以帮忙内推一下analog/mixed signal IC的
intern,明年1月或者暑假开始都可以。感激不尽!

本科的時候見到p n junction和cmos就想吐,所以選了signal processing。現在在上
碩士的introduction to statistical processing的課,基本都是數學題,好多統計。
這次作業8道題,我做了一下午,看了前六題,就有兩道不會。
數學不好到底應該怎麼破啊?

拜托,A、B、C三科,A是的B先修,B是C的先修,那就别想在一个学期内一次读
完三科,会死人的
Introduction to Real Analysis must be studied first. Then sigma algebra (
theory; just get familiar with the notations). Finally intro to statistical
signal processing.
