I. MOTIVATION FOR RESEARCH Recently, the use of high-speed permanent magnet synchronous motors (PMSMs) has become prominent owing to their high efficiency, simple structure, high power density, and small size [1–2].
A multilevel back-end-of-line structure with a dielectric constant κ ≤ 2.4 ultra low-κ materials was developed. κ=2.2 ULK build was demonstrated at a 144nm wiring pitch and a κ=2.4 ULK was demonstrated at a 288nm pitch. Good model-to-hardware correlation for the measured capacitance indicated no significant plasma damage to the ULK 2.2 material. The extracted copper resistivity was consistent with...
Given a contraint on the total amount of feedback overhead, we investigate the allocation of feedback bits (i.e. codebook sizes) among users in a limited feedback Zero Forcing Beamforming-based MU-MIMO scheme where users have the opportunity to adapt their codebooks as a function of their own channel statistics. We consider both single-polarized and dual- polarized scenarios. Using upper bounds on...
