Abstract :
The analog power amplifier (PA) control loop of a fully-integrated GSM/GPRS quad band transceiver by Duvivier et al. (2003) is presented. The control loop is based on a fully-integrated PA controller which meets all GSM/GPRS specifications. Both the gain and the bandwidth of the PA control loop are programmable as well as the stand-by voltage delivered to the PA. These features, together with a high driving capability (8.4 mA @ 2.5 V), make this solution capable to interface vast combinations of PAs, couplers and detectors. The proposed PA controller has been integrated in a BiCMOS SiGe 0.35 μm process and measures 0.33 mm2. The current consumption is 2.8 mA without load and 7.2 mA in the application (using Hitachi PF08109B PA) from a single 2.8 V power supply.
