The previous numerical matching method can't apply in the whole angle space (0° ≪ β0 ≪ 90°) whether only based on the normal incidence case nor based on grazing to the edge incidence case when solving the diffraction problem of the anisotropic impedance wedge at oblique incidence by plane wave. A revised numerical matching method (NMM) based on the framework of the uniform geometrical theory of diffraction(UTD)...
Electroglottograph (EGG) is a non-invasive way to measure the vibration of vocal folds in terms of electrical impedance. In present work, age group classification of male subjects has been performed by analyzing the EGG and its corresponding first order differential Electroglottograph (DEGG) signal. Glottal Closure Instant (GCI) and Glottal Opening Instant (GOI) are derived from DEGG signal. Perturbation...
This paper presents a quad-lane serial link that supports virtually all data center system-side and line-side communications standards from 8.5–13 Gbps, implemented in 28 nm CMOS. The Tx is series source terminated with a 4-tap FFE. Its swing ranges from 33 mV to 1 Vppd. The Rx has CTLE, 5-tap DFE and CDR with 2x-oversampling, and baud-rate timing recovery options. At 13 Gbps, the link can equalize...
