Abstract :
For successful implementation of a multi-standard transmitter, reconfigurable transmitter architecture and component design are essential. This paper presents a reconfigurable CMOS power amplifier with flexible matching network which is designed in CMOS 0.25um process. The designed power amplifier can be operated at 0.9, 1.2, 1.75, and 1.85 GHz. Also, this can be used at 2.4 GHz by using bonding wire inductor. The flexible matching network is applied at the interstage matching and composed of two inductors and four switches. By controlling four switches, operation frequency of the interstage matching can be varied. Proposed amplifier can be used as a power amplifier in low power applications such as ZigBee or Bluetooth.
