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(More)

We report a 5.4 mW ultra low dc power low noise amplifier (LNA) at 5.5 GHz, which is based on a 0.35-mum BiCMOS technology. The trade-off between the NF and linearity for LNA circuit design has been investigated. Furthermore, the usage of the HBT-cascade-MOS methodology is simultaneously satisfied the tradeoff between noise figure (NF) and linearity of LNA.(More)
