With the MENS evolution and the interest it is getting in the industry. I see a great and solid future for analog. From the front-ends to the internal circuits, analog is a key part of MEMS. Digital comes at the downstrean. The reason why analog seems not to be popular is not because we do not need it, but it is simply expensive to develop and make money with.

Re: Challenging the Status Quo
The simply fact is that the world is analog. So, when you do all the digital stuffs, you need to operate in the analog realm. That is how Analog Devices has remained in the business of converters for a very long time.

Only the folks in Wall Street think that way. They always punish the analog firms and reward the digital ones. I am yet to understand the basis for all these valuations that punish analog and make digital great.

Some Questions
How safe will be completely dedicated to developing something?

How much I have to invest in order to maintain the production of something so specific.?

Well some questions that might be relevant. I am not against this type of technology, provided that there is a way to open the competition against my own project, and not get extremely hands on the manufacturer.

Re: Fundamentals
The noise issue is especially troubling, especially if your doing audio. Glad I don't have to do the IC design - that's way being my ken.

Fundamentals
There is a fundamental reason why digital circuits scale better than analog circuits in modern technologies. All a digital guy needs is speed, speed and speed. Switches and capacitors get smaller and faster in each technology node. But for analog, smaller is not always better. Namely, smaller means more (flicker) noise, more offset and less linearity. Not to mention the voltage headroom. So the higher speed comes with less accuracy. The challenge for the analog circuit/system designer is to come up with solutions that trade this speed for accuracy.

What's the cost?
Sounds like you're angling for the creation of an analog ASIC service industry to arise. The question I would have is "What's the cost?" It seems to me that mask costs for these highly-integrated  analog parts would be much less than today's diigtal ASICs, so that shouldn't be an impediment, but the test costs could be pretty high.

This could be an interesting turn in the analog design world. Companies are starting to create analog front ends for key applications, just as they have digital ICs for those key applications. Things in digital move from ASIC to ASSP, to stock chip. Having analog circuitry able to follow the same trajectory might well be the way things go from here.

Re: Challenging the Status Quo
Innovation is alive and well in the analog world. Without analog knowledge, most digital circuits turn to mush. It;s the analog signal processing in electrical and optical transceivers that make the high digital data rates possible. Complex modulation such as QPSK (see contellation diagram) used in today's 10Gbps and higher digital lanes is all based on RF and analog concepts. At such high speeds, digital turns to analog.

Challenging the Status Quo
Great idea for a blog. Innovatioin is sorely lacking in the analog world, I supposed because so many people think the digital side is all that really matters and is where the "new" stuff happens.  But I firmly agree it is unacceptable to say "it can't be done" unless you add the word "yet."
