In this work, two radio frequency (RF) voltagecontrolled oscillators (VCOs) are evaluated to determine feasibility for use in a high data rate wireless LAN. Designs are presented for a Colpitts oscillator and a differential L-C oscillator operating at 10GHz. The circuits are to be fabricated in a 3.3V 47GHz SiGe BiCMOS process, pushing the limits of the(More)
A new quality factor enhanced resonator core is presented and used to design a bandpass filter at 2.4GHz. The new Q-enhanced LC-tank has independent Q tuning capability, which substantially simplifies the automatic Q-tuning problem. In simulation, the unloaded Q-enhanced core consumes 7.05mA from a 1.8V supply in 0.18/spl mu/m CMOS and can be tuned from(More)
The design of a simple IF subsampling terminal for a gigabit wireless local area network is presented. All equalization is performed in the base station, allowing the terminal to be implemented using simplified hardware without any digital signal processing. System design of the WLAN terminal is discussed and simulation results are presented for an SOC(More)
Bluetooth is a communications standard targeting shortrange wireless communications with data rates of 1Mb/s at 10m distance. To encourage Canadian universities to pursue this commercially promising standard the Canadian Microelectronics Corporation is providing the intellectual property for a Bluetooth SOC Reference Platform. This platform does not(More)
