Abstract: 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.

Key words: Bluetooth, configurable, serial control interface
