| Outline of Final Research Achievements |
Novel power amplifier and voltage-controlled-oscillator (VCO) ICs are designed, fabricated and fully evaluated using Si CMOS technology for realizing solar cell powered ICs. The fabricated power amplifier IC has exhibited an output power of 5.0 dBm and an efficiency of 29 % at a supply voltage of 0.5 V at an operation frequency of 2.5 GHz. The fabricated VCO IC has achieved minimum operation voltage of only 0.28 V which is the top level in state-of-the-art VCO technologies. In addition, the VCO IC exhibits an oscillation frequency range from 2.1 to 2.3 GHz at a supply voltage of 0.5 V.
Therefore, measured performance which exceeds the goal of this study has been obtained.
