Analog Design

Objective::

It's required to design a differential amplifier with the following specs:

=EF=83=BC Gain 20 =EF=83=BC Integrated input referred noise < 1mV =EF=83=BC B.W. 10 MHz =EF=83=BC For i/p 2 Vpp swing =C3=A0 THD=3D1% =EF=83=BC Design CMFB =EF=83=BC Minimum power =EF=83=BC Vdd=3D3V

Deliverables:

-Choose any suitable architecture ( transistors should be MOS ), make your design calculations and hand-over a hard copy including full schematic with all values clear and justified.

-Use any simulation tool to verify your design, If you use Cadence tool it will be a plus (you will get bonus points) and hand over a hard copy of your simulation results.

-Creative thoughts for design optimization will be rewarded.

Aha! HOMEWORK!

Poor baby! Cadence tools are over-priced crap ;-)

Do _I_ get the A ?:-)

I suppose paying a contractor to do your work isn't the sort of 'creative thoughts' they were looking for.

How do these people think they're going to do their jobs when they graduate? Or are they planning on going straight into marketing or management?

Looks like management material to me ;-)

Jim -- you should quote the guy your standard rates; you never know how rich and/or desperate he is. :-)

When I was in graduate school we had a gen-u-ine prince from the middle east (?) in the EE department... nice enough guy, although the department's director was telling me once how she almost felt like the guy's mother a bit at times since she had to explain to him things like, "No, you can't have a homework deadline extension because you're chartering a private jet to see a concert in Atlanta this weekend..." :-) I believe he did graduate and all -- apparently he'd almost never been told "no!" before in his life, but he did have a good work ethic.

His professor should give more points for, "Perform the design simulation using the Cadence tools; now do the same things in the toolset of your choosing. Demonstrate why Cadence is over-priced..." :-)

I actually had a guy offer to pay my standard rate to finish part of his Master's project. I told him "sure, as soon as I've cleared it -- what's your advisor's name again?".

I never heard from him again...

We had a Columbian Army officer in my MIT undergrad class. Wealthy, married, multiple kids, had a maid, etc. But he was a really nice guy, did all his course work himself, and served fabulous coffee ;-)

Also in my class were multiple Cubans, upper middle class, scared about Castro taking over ;-(

Sno-o-o-o-ort!

Couldn't you just buy the differential amplifier?

Objective::

It's required to design a differential amplifier with the following specs:

? Gain 20 ? Integrated input referred noise < 1mV ? B.W. 10 MHz ? For i/p 2 Vpp swing à THD=1% ? Design CMFB ? Minimum power ? Vdd=3V

Deliverables:

-Choose any suitable architecture ( transistors should be MOS ), make your design calculations and hand-over a hard copy including full schematic with all values clear and justified.

-Use any simulation tool to verify your design, If you use Cadence tool it will be a plus (you will get bonus points) and hand over a hard copy of your simulation results.

-Creative thoughts for design optimization will be rewarded.

Have you looked in your textbook and lab notes?
