| Abstract: | Introduced a novel CMOS power amplifier, which not only gains high efficiency like switch power amplifier, but also gains the ability to output variable envelope carrier like linear power amplifier. Output power of the amplifier is proportional to the digital control bit. The circuit is designed and manufactured in 0.6 μm CMOS process. Test results indicated the transmitter does work well under the temperature from -20°C to 80°C with supply voltage ranged from 2.5 V to 5.5 V; Output power of the transmitter covers a wide range; The maximum output power of the amplifier can reach 6.25 W under supply voltage of 5 V. |
