摘要: In this paper, the design and application of an on-chip transformer balun for RFIC has presented. Single-ended primary differential secondary are constructed without using three individual windings simple layout. Besides, new topology same physical common visual ground point second winding, which eliminates imbalance due to potential difference at from conventional trifilar. Furthermore, is successfully applied in integration 5.8-GHz LNA-mixer implemented on SiGe 0.35-/spl mu/m BiCMOS process then achieves 4.15-dB noise figure (NF), 34.61-dB conversion gain, -9.5-dBm input third-order intercept-point with low power consumption 9-mW.
