Abstract:This paper proposes a high efficiency power amplifier with a diode linearizer and voltage combining transformers in a standard 0.13-μm TSMC CMOS technology. The 3-D simulated transformer adopts multi-finger architecture which provides low insertion loss and allows high current capacity on the transformer. With the 4 differentially cascaded connected multi-finger transformers, the amplifier delivers more than 1W output power under 1.8 V supply condition. To enhance linearity of the power amplifier, the diode co… Show more
