This article reports the experimental evaluation of a 0.24-mum CMOS technol
ogy for Bluetooth power applications. From load-pull measurements, the 0.24
-mum CMOS power transistor can deliver 23 dBm output power with 39 percent
PAE at 2.4 GHz. A modified BSIM3v3 RF model with a new substrate network is
presented for the design of Bluetooth power amplifiers. The simulation res
ults of the proposed model show better agreement with the S-parameter and l
oad-pull measurement results than several previously reported BSIM3v3 RF mo
dels.
