Analog-centric RFCMOS technology has played an important role in motivating the change of technology from conventional discrete device technology or bipolar IC technology to CMOS technology. However it introduces many problems such as poor performance, susceptibility to PVT fluctuation, and cost increase with technology scaling. The most important advantage of CMOS technology compared with legacy RF technology is that CMOS can use more high performance digital circuits for very low cost. In fact, analog-centric RF-CMOS technology has failed the FM/AM tuner business and the digital-centric CMOS technology is becoming attractive for many users. It has many advantages; such as high performance, no external calibration points, high yield, and low cost. From the above facts, digital-centric CMOS technology which utilizes the advantages of digital technology must be the right path for future RF technology. Further investment in this technology is necessary for the advancement of RF technology.
