• 論文の詳細を見る

• This paper describes a low-powcr-supply 2-GHz CMOS up-converter. A current-mode mixing method using current adding and self-switching mixers is proposed for 1-V operation. The currentmode up-converter achieves conversion gain of 6.7dB and linearity of 6.5-dBm OIP3 at 1V. Balanced configuration and DC offset canceller reduce LO leakage below -40dBc even with 20-mV V_<th> mismatches. The bias circuit of the IC is designed to maintain constant conversion gain for variation of temperature for practical usage. The measurement results indicate the proposed up-converter is applicable for future wireless systems.
