摘要

提出了一种低功耗5.2 GHz同步振荡器。该SO完全采用0.25 μm SiGe BiCMOS技术实现，专用于802.11a WLAN应用。利用体效应提供了一个可调谐振荡器，以控制自由运行的振荡。在1.8 V电源和5.2 GHz下，SO的核心在载波100 kHz时消耗9 mW，相位噪声为-114 dBc/Hz，并提供400 MHz同步带宽。

A 5.2 GHz tunable synchronous oscillator for IEEE 802.11a applications

A low power 5.2 GHz Synchronous Oscillator (SO) is presented. This SO has been fully implemented in a 0.25 μm SiGe BiCMOS technology and is dedicated for 802.11a WLAN applications. The use of body effect provides a tunable oscillator in order to control the free running oscillation. Under 1.8 V supply and at 5.2 GHz, the core of the SO consumes 9 mW for a -114 dBc/Hz phase noise at 100 kHz from the carrier and offers 400 MHz synchronization bandwidth.
