    Market in Singapore for Analog IC design

    I can say singapore is not the right place to do IC Design. There are only 10 -12 companies. And then there are many graduates coming out of universities say 100 per year with ic design as their major. In terms of quality, I cannot comment. So the companies can chose from a bigger pool and there...

    where to download berkeley webcast courses except there?

    eecs 242 webcast You can search for EE142. Its same as E242 (RFIC). EE142 is for undergrad and EE242(grad). Same course notes and same class,but former will not do a project,latter will do a project for credits. I think u can got Dr. Ali Niknejad website to download lecture notes and project...

    need help in designing opamp

    Suppose I know that my gain is around 90 dB and fu is 1 M Hz. How will we decide the currents. Share some methodology. Can we do anything with ICMR and OCMR. Thanks in advance.

    need help in designing opamp

    design steps for op amp Suppose , I have only the specificatin of DC open loop gain and Common mode gain and ICMR and OCMR. How will I proceed to design the opamp. I need a high gain opamp,so I chose Miller opamp. But I would like to know,how will we decide the currents.(no slew rate is given).

    Suggest me a method of sense conductance over 10 to 50 nano

    sesnse conductance hi Can anyone suggest me a method to sense conductance over 10 nano siemens to 50 nano siemens. Or else any method to sense resistance between 1 Mega Ohm to 40 Mega Ohm. I must detect 1% variations. Thanks in advance

    urgent soultion needed

    hi, I have been given a task to design a signal conditioning circuit. I have the sensor macro model. It is modelled as VOltage controlled resistor. Can anyone please suggest me references,books dealing with such a stuff. I want from basics. Thanks in advance.

    need help on sensor signal conditioning circuit

    I donot have any specification of the sensor. I am aksed in a way to design for a device that is non existing.I will get only the electrical specifications. I would like to know references on the usage of wheatstone bridge. And also on instrumentation amplifier. Thanks in advance. Added...

    What is the usage of source follower?

    U can use source follower for isolating i.e., in Common mode Feedback(see Chap 16. of Gray & Meyer). This is all on voltage side. Instead it can be used as a current amplifier. Common usage is voltage buffer(Av=1)

    how to start a ADC design

    Please help by providing any reference document for any ADC design. How will we decide the architecture? How will we design the comparators,opamps i.e., how we will decide their Unity Gain Bandwidth etc

    why vdsat can be lower for submicron cmos process? eg. vdsat

    vdsat in strong inversion Please go through any MOEFET physics books,u will come to know. Read velocity saturation in that,and look at the curve,it resembles as our Drain current. As we reduce the power supply for DSM. we also reduce VDSAT,i.e., we will have strong inversion for low...
