摘要

介绍了用于IMT-2000频段的2ghz lc振荡器的设计。lc振荡器有一个简单的自动摆动控制电路，为混频器和预分频器提供恒定的输出功率。整个电路由振荡器芯、缓冲器、带隙基准和驱动放大器组成，振荡器芯消耗1.3 mA。频率调谐范围约为360mhz。lc -振荡器的输出功率在1.1 dBm以内。该芯片采用ST微电子公司的60 GHz SiGe BiCMOS工艺实现。在2.7 V单电源下，总功耗为31.5 mW。

A 2 GHz LC-oscillator with automatic swing control for IMT-2000 application

Describes the design of 2 GHz LC-oscillator for IMT-2000 frequency band application. The LC-oscillator has a simple automatic swing control circuit for providing constant output power to mixer and prescaler. Total circuit consists of oscillator core, buffer, bandgap reference and drive amp. The oscillator core consumes 1.3 mA. A frequency tuning range is about 360 MHz. The output power of the LC-oscillator varies within 1.1 dBm. This chip is implemented in 60 GHz SiGe BiCMOS process by ST Microelectronics. Total power consumption is 31.5 mW at a 2.7 V single power supply.
