摘要

介绍了一种用于IEEE 802.11b直接转换接收机的低功率压控振荡器(VCO)。VCO由台积电0.25-/spl mu/m制造;根据测量结果，调谐范围为187 MHz (7.78%);2.4GHz时相位噪声为-73.62dBc/Hz@600 kHz偏移和-82.44dBc/Hz@1MHz偏移。该电路仅从1.5V电源为VCO核心吸取53/spl mu/A电流。

An ultra low power 2.4GHz CMOS VCO

A low power voltage-controlled oscillator (VCO) for IEEE 802.11b direct conversion receiver is demonstrated. The VCO is fabricated by TSMC 0.25-/spl mu/m; based on the measurement results, the tuning range is 187 MHz (7.78%); phase noise is -73.62dBc/Hz@600 kHz offset and -82.44dBc/Hz@1MHz offset at 2.4GHz. The circuit draws only 53/spl mu/A current for the VCO core from a 1.5V supply.
