The watt-level CMOS PAs in millimeter-wave frequency regime seems to be far away today, but might be achievable in the near future, especially with the new concept of CMOS device, passives, and the design techniques. To achieve a high power MMW CMOS PA, many efficient N-way CMOS power combining architectures have been proposed.In this talk, we will compare the saturated output power (P_sat) and chip area of output stage for (a) Wilkinson PA, (b) transformer-based PA, and (c) other potential N-way combining PA.To maximize the output power per chip area, we will also study the CMOS device power/current density of different advance CMOS process.Due the limitation of the current carrying capacity of metallization in CMOS processes, system-in-package/3DIC designs are also considered for high-power CMOS PAs.Another design challenge of MMW PA is the stability issue from low-frequency to the highest CMOS f_T/f_max frequencies.A number of high-power PA stability problems, such as odd-mode oscillation, bias-network feedback, and output load mismatch, will be analyzed for MMW PA.The case study of MMW PA instability will also be given in this talk.
