Summary: 
Mixed-signal LSIs promise to permit increased levels of integration, not only in voiceband but also in multi-GHz-band applications such as wireless communications and optical data links. This paper reviews the evolution of mixed-signal communications LSIs and discusses some of their design problems, including device noise and crosstalk noise. In the low-power and low-voltage designs emerging as new disciplines, the target supply voltage for voiceband LSIs is around 1 V, and even GHz-band circuits are approaching 2 V. MOS devices are expected to play an important role even in the frequency range over 100 MHz, in the area of wireless or optical communications circuits.
