## Abstract A 1.9โ€GHz CMOS differential power amplifier for polar transmitter applications is designed using a 0.25โ€ฮผm RF CMOS process. The input transformer and output transformer are fully integrated on the chip. The transmission line transformer is used as an output power combiner and an output
