Abstract

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