A Fully-integrated 5 GHz 0.18 µm CMOS VCO for 802.11a WLAN Applications

This article presents a fully-integrated 5 GHz CMOS voltage-controlled oscillator (VCO) for a U-NII band 802.11a WLAN application. The VCO core circuit uses only PMOS fabricated with the 0.18 mm 1P6M standard CMOS process to obtain better phase noise p...
Due to the fast growing demand for broadband wireless communications, the operating frequency is moving toward the 5 GHz U-NII band. With a maximum data rate of 54 Mbps, the IEEE 802.11a wireless LAN (WLAN) standard specifies a 300 MHz allocation of spectrum in the 5 GHz range that...
