Weiping Wu, Xun Bao, Shulan Chen, Yan Wang, Lei Zhang The schematic of the prototype PA using the proposed TCL-based CGB technique is shown in Fig. 32.4.3. The PA consists of a CS output stage, a TCL-based CGB driver stage, and a hybrid TCL-based CGB input stage. A distributed balun is employed for broadband and efficient output matching. The input and driver stages achieve a complementary gain response versus the output stage by the proposed CGB technique. An LC and a coupled-line-based networks are incorporated for inter-stage matching and slight gain adjustment. Implemented in a 65nm CMOS technology, the PA occupies a core area of 0.039mm2. Tsinghua University, Beijing, China The ever-growing demand for high-speed data links and innovative applications has driven the rapid development of millimeter-wave (mm-wave) technologies. In recent years, the 70/80/90GHz bands have been proposed and applied for high-speed wireless
