摘　　要：针对蓝牙射频系统,给出了一种模拟参数可重置的结构及电路实现,该电路结构巧妙,占用的引脚少,完全能够和射频模块集成.流片结果显示,芯片各模拟参数重置和电路测试正常,有效保证了蓝牙射频前端各模块的功能和性能.In the design of such RF integrated circuits as Bluetooth, switched capacitor arrays is used and both the output power of a power amplifier （PA） and the center frequency of a frequency synthesizer must be adjustable. They need some kind of digital control. In this paper, a configurable architecture for Bluetooth is presented, in which various analog parameters can be set freely. The core circuit is described in detail, which is smartly designed and takes very few pins. The tested result shows that all the analog parameters can be set properly, ensuring the functions and performance of RF building blocks in Bluetooth.
