This project presents a sub-mW FM radio receiver for mono-audio applications. The chip functionality has been experimentally verified with the FM signals from commercial radio stations. The important parameters of the chip are shown in Tab.1, along with the specs of a commercial FM receiver chip, Si4702, for comparison.

The authors would like to thank many colleagues and advisors, who helped us a lot along the way. In particular, Prof. Peter Kinget (Columbia University) is acknowledged for guiding us the project. Vivek Mangal (Columbia University) and Yang Xu (Columbia University), as our teaching assistants, are thanked for patiently answering our questions about the schematic design and the layout design. Jianxun Zhu (Columbia University) is acknowledged for suggesting low-voltage topologies for the cascaded limiter amplifier.
