【Abstract】 A traveling-wave amplifier (TWA) with lossy transmission line was discussed. An integrated CMOS TWA with lossy on-chip spiral inductor was designed with 0.18 μm CMOS process, the simulated gain is over 15 dB on 14 GHz bandwidth. Besides, the gain of TWA versus the distributed parameters of lossy on-chip spiral inductor was simulated, and the simulated results have some guideline to the optimizing design of TWA.更多还原
