Abstract :
On-chip transformers with high mutual coupling factors (~0.9) are designed and characterized. The transformers are integrated into a 5.0-GHz receiver front-end to provide single-to-differential conversion and voltage gain. The CMOS receiver frond-end exhibits a voltage gain of 25.0 dB and an IIP3 of -5.9 dBm at 5.0 GHz at a power consumption of 36 mW.
