Linearization of a 65nm CMOS Power Amplifier with a Cartesian Feedback for W-CDMA Standard
Résumé
A study based on improving linearity of an integrated RF power amplifier (PA) has been done for W-CDMA standard. This power amplifier had been designed in 65nm CMOS of STMicroelectronics under Cadence. The chosen linearization technique is a Cartesian Feedback (CFB). Thanks to this linearization technique, the ACPR has been improved by 22dB at 5MHz from the carrier for an output power of 18dBm.
