Wireless communication has grown, exponentially, with wide range of applications offered for the customers. Among these, WLAN (2.4-2.5GHz, 3.6-3.7GHzand 4.915- 5.825GHz GHz), Bluetooth (2.4 GHz), and WiMAX (2.500-2.696 GHz, 3.4-3.8 GHz and 5.725-5.850 GHz) communication standard/technologies have found largest use local area, indoor – outdoor communication and entertainment system applications. One of the recent trends in this area of technology is to utilize compatible standards on a single chip solutions, while meeting the requirements of each, to provide customers systems with smaller size, lower power consumption and cheaper in cost. In this thesis, RF – Analog, and – Digital Integrated Circuit design methodologies and techniques are applied to realize a multiband / standart (WLAN and WiMAX) operation capable Voltage- Controlled-Oscillator (VCO) and Frequency Synthesizer. Two of the major building blocks of wireless communication systems are designed using 0.35 μm, AMS-Bipolar (HBT)-CMOS process technology. A new inductor switching concept is implemented for providing the multiband operation capability. Performance parameters such as operating frequencies, phase noise, power consumption, and tuning range are modeled and simulated using analytical approaches, ADS® and Cadence® design and simulation environments. Measurement and/or Figure-of-Merit (FOM) values of our circuits have revealed results that are comparable with already published data, using the similar technology, in the literature, indicating the strength of the design methodologies implemented in this study.
