چکیده
A DC-offset cancellation scheme in the 5GHz directconversion receiver compliant with IEEE 802.11a wireless LAN standard is described in this paper. It uses the analog R~F4~~ i"a I oU feedback loop to eliminate the DC-offset at the output of the double-balanced mixer. The mixer has a simulation voltageA conversion gain of 13dB at 5.2GHz, noise figure of 9.67dB, -. 1) IIP3 of 7.6dBm. The solution provides 39.1dB reduction according to the leakage value at LO and mixer load resistors, LNA Mixeur L_ the additional noise figure added to mixer is less than 0.9dB, 1 R band the added power dissipation is 0.1mW and was fabricated in 60GHz 0.35,um SiGe BiCMOS technology.

متن کاملAdjacent Channel Interference Cancellation Scheme for Low-IF Receiver in Multi-Channel Reception
In this paper a new adjacent channel interference (ACI) cancellation scheme for multi-channel signal reception with low-IF receivers is investigated through the experiment. In the low-IF receivers, the signal in the mirror frequency causes interference to the desired signal. In the proposed analog-digital signal processing scheme, channel selection is made by analog complex band pass filter and...
