Tóm tắt

This paper presents a direct conversion fully integrated receiver for 5 GHz wireless LAN fabricated in a 0.18 /spl mu/m CMOS technology. It combines low-noise amplifier, mixer, integer-N frequency synthesizer, automatic gain control, low pass channel-select filter, and analog-to-digital converter. The cascade noise figure is 8 dB, and the cascade IIP3 is -7.05 dBm. In active mode, the receiver drains 90 mA on average from a 1.5 V supply.
