| Popis: | 95 In this thesis, we introduce three subjects about wireless communicational RF circuits. First, Weaver-Hartley image rejection down-converter using the architecture of complex mixers and complex filters is designed to reject image signals. The Weaver-Hartley image rejection down-converter using low-IF architecture is designed to be dual-band system. Second, Marchand Balun and Gilbert mixer are combined into wideband circuits. Third, we introduce the sub-harmonic mixer, frequency doubler, micromixer, single quadrature down converter and double quadrature down converter. The dual-band Weaver-Hartley image rejection down-converters are designed by using TSMC 0.35μm SiGe BiCMOS and TSMC 0.18μm CMOS technologies. The wideband mixers with Marchand Balun are designed by using TSMC 0.35μm SiGe BiCMOS and TSMC 0.18μm CMOS technologies. Finally, the high-frequency mixers are designed by using WIN 0.15μm PHEMT and MHEMT technologies. |
