Abstract

This paper discusses the constraints set by device dimensions and cross-coupling capacitance on the power gain, bandwidth, and noise performance of millimeter-wave common-source pairs fabricated in CMOS processes. The analysis is backed by simulation of 28nm bulk-CMOS cores at W-band frequencies (70GHz-110GHz). The paper also proposes a new transformer geometry for improving the quality factor of very small transformers.
