Abstract

An innovative topology for 5G mm-Wave harvesting is proposed, using 65 nm CMOS. The rectifier circuit is based on a cross-coupled differential core that is enhanced by the addition of harmonic suppressing capacitors. Presented, are two versions of the topology, one with LVT and the other HVT transistors achieving a peak power conversion efficiency (PCE) of 40% at 0 dBm input power and 42% at 10 dBm input power, respectively. The circuit occupies as area of 130 X 200 $\mathbf{\mu} \mathbf{m}^{2}$ and is targeting the 5G NR FR2 band between 26.5 GHz and 29.5 GHz.
