摘要（英）：

The present invention relates to a micro CMOS power amplifier, in which an output transformer is configured as a substrate of a multilayer structure, and an amplifier circuit module is stacked on the output transformer. The micro CMOS power amplifier includes: an amplifier circuit module chip configured by modularizing circuits for amplifying power as a module; and an output transformer for outputting output of the amplifier circuit module chip to outside through a transformer circuit, in which the output transformer is implemented on a multilayer substrate, and the amplifier circuit module chip and the output transformer are configured as a stack. According to the micro CMOS power amplifier of the present invention described above, an output transformer occupying a large space in a conventional power amplifier is configured as a multilayer substrate, and thus the chip size can be reduced within 50% without decreasing output power of the power amplifier.
