| Resumo |
A DC-offset cancellation scheme in the 5GHz direct-conversion receiver compliant with IEEE 802.11a wireless LAN standard is described in this paper. It uses the analog feedback loop to eliminate the DC-offset at the output of the double-balanced mixer. The mixer has a simulation voltage conversion gain of IMB at 5.2GHz, noise figure of 9.67dB, IIP3 of 7.6dBm. The solution provides 39.1dB reduction according to the leakage value at LO and mixer load resistors, the additional noise figure added to mixer is less than 0.9dB, the added power dissipation is 0.1mW and was fabricated in 60GHz 0.35 mu m SiGe BiCMOS technology.
