Hi

I am Newbee in Analog IC design.

I have few doubts. Please let me clear in those.

1. Like digital IC design using VHDL/Verilog, is there any particular programming language for analog IC design. If so, what are those? where we have to program?

2. What are the tools used for analog IC design? what are the features and specifications?

3. After designing analog system IC in PC using some specified tools, how can it be fabricated?

4. What abt temperature, noise and other analog parameters considerations in designing an analog IC.


Thanks in advance,
Vishwa

there are no such tools for designing analog ic design

u have to do manually

bcz lot of atching issues have to be taken care

Fully custom design for analog...

We dont have tools for generating the layout like verilog in ANalog design..first of all, transistor is not at the same size..it's accordign to the need of it, wheter to be diode, resistor or capacitor it sellt

In Analog device matching is very vital...LAyout usually drawn by the designer itselft using spec from the netlist...summary: Analog design need to be accurate and roboust b coz it's the interface for real world(analog) and processing unit(digital@comp)

2. What are the tools used for analog IC design? what are the features and specifications?

Usually the tools is similar to digital, starting from MATLAB for the architecture to meet the spec, to transistor netlist (usually Star_Hspice) then to LAyout.
Cadance Virtuoso is good tools...

The features and spaec is according to the demand, if it's for comm device then high speed is the aim with moderate resolution...

If it's for sensing or medical...then high precission and resolution is more concern than the speed

The challange is to get high speed and high resolution device...people are working on it nowadays.


3. After designing analog system IC in PC using some specified tools, how can it be fabricated?

Using the same fab like digital, no difference..only the masking is differ


4. What abt temperature, noise and other analog parameters considerations in designing an analog IC.

Serious measure must be taken..back to the precission fact..now Analog is more to mixed signal design..people try to detect different from maybe a blood cell with few micron volt, then our amplifier must be able to sense that and must be able to amplify it the the level that can be processed by digital device..for example

well that's depend on the level of simulation
are you talking about system level design ? if yes then go use MATLAB along with good book on such thing note we are talking about analysis not synthesis such as this
Electronics.And.Circuit.Analysis.Using.MATLAB.rar.html PASSWORD: Password: www.AvaxHome.ru

download it from
http://please log in to see links/

if we are talking about transistor level simulation then VHDL-AMS or pspice can be used again this is just an analysis

if we are talking about interface requiorement for such IC power, current,...etc then IBIS language can be used for that
have fun
