| The future of mixed-signal design
|
2000-02-01 |
| I hear two contradictory things regarding mixed-signal IC design. One set of voices says the systems-on-chip (SoC) of the future will be large mixed-signal systems, and the proportion of these being built will double from about 33 percent currently to 66 percent by 2005. The other set of voices says everything will be big digital chips constructed in ever-deeper submicron CMOS, in that the ASICs of the future will use as many 15 million logic gates, but that the analog and mixed-signal circuitry will be left off-chip. |
