This paper presents a performance comparison method among the circuits for different high-frequency communication systems using newly proposed figure of merit (FOM). Efficiencies of transmission energy of circuits for optical communications, cellular phone systems, and ubiquitous network systems are compared by the FOM. The FOM expresses the circuit performance among the different communication systems without the influence of the difference of the communication capacity and the device performance. The FOM of the circuits are plotted in the almost equal value without depending on system differences, and the differences indicate the technical evolutions of the systems and circuit designs.
