Speeding Up or Slowing Down

Re: Speed up or Slow down?
I think the economics for the digital part of the design has been the drive up to this point. More transistors on a chip means cheaper transistors in general. In the bigger picture this also means greater opportunity for integration. Mors of what were oin seperate chips are now within one chip and so this eventually created the pull to bring abalog on chip as well. But if analog does not scale in the same way, then while there is the pull for greater integration, there is a push becqause analog will consume a greater percentage of the chip area, meaning that its percentage of the total cost will rise. So, the balance point is tricky and involves not just cost, but overall system performance - will the extra slowdown of going off chip bring the performance below a necessary threshold. 3D IC may help solve this problem but today it is too expensive a solution for most people and situations.

Re: Speed up or Slow down?
Brian, you ask a profound question. To answer it, perhaps the screen needs to be moved back a ways to look at the larger picture. That picture, to me, shows a certain amount of tunnel vision in the electronics industry, in the singular drive (or mad rush, if you will) toward smaller, denser ICs, and neglect of what to do with all those transistors. I would rather have 200 nm transistors and some clever, innovative circuitry than more transistors than I know what to do with that are overly constrained by quantum effects.

Re: Speed up or Slow down?
I think it is some what true that adoption to new technology is speeding up for digital. But we cannot ignore the development on side of analog in the era of Software Defined Radios and Direct Digital Synthesis. These are the devices that are available now, which were just dreams few years ago. So, there is definitely a development on both analog and digital side. There is mixed signal domain which is emerging. Probably there should be a Moore's law for mixed signal ICs.

@Bill that was great thanks for sharing it, I'm pretty its going to replace the analog, today's market demands manufacturers build smaller components with more integrated functionality, better product efficiency and competitive advantage.

Today's engineers are spending more time and attention on new materials and structures, trying to look for new development and efficiency- I think replacing an old methods or technology with new one is crucial to industry's survival and growth.
