5.7 GHz 0.25 μm CMOS RF Front-end Circuits for an IEEE 802.11a WLAN Receiver

A 5.7 GHz 0.25 mm CMOS RF front-end, including a CMOS differential LNA and a CMOS Gilbert-cell mixer, for an 802.11a WLAN receiver is presented. The differential LNA, fabricated with the 0.25 mm 1P5M standard CMOS process, utilizes a current-reuse tech...
Due to the growing demand for broadband wireless communications, the operating frequency is moving toward the 5 GHz U-NII band. The advantage of combining the baseband circuitry and the RF front-end on one single chip for cost savings is strongly desired for highly integrated system-on-chip (SoC) applications. Due to...
