A 60GHz 1V + 12.3dBm Transformer-Coupled Wideband PA in 90nm CMOS

We demonstrate a fully integrated 60GHz transformer-coupled two-stage differential power amplifier with single-ended input and output in 90nm digital CMOS with no RF process options. This work uses on-chip transformers for a 60GHz PA as an integrated CMOS solution. Operating from a IV supply, it achieves a ldB compressed output power of +9dBm and saturated power of +12.3dBm.
