Machine-learning prediction of the d-band center for metals and bimetals

open access: yesRSC Advances, 2016
The d-band centers for eleven metals and their pairwise bimetals for two different structures (1% metal doped- or overlayer-covered metal surfaces) are statistically predicted using machine learning methods from readily available values as descriptors for the target metals.

A D-Band Amplifier in 65 nm Bulk CMOS for Short-Distance Data Center Communication

open access: yesIEEE Access, 2018
A novel pole-tuning technique with T-type network for interstage bandwidth extension is proposed in this paper. By exploiting the proposed technique in interstage of amplifiers, the transfer function of each stage exhibits two dominant poles, achieving a flat gain-frequency response over an ultrawide bandwidth.
