Normal function of the dopaminergic system is necessary for speech fluency. There was evidence that the activities of dopamine transporter (DAT) and dopamine D2 receptor (DRD2) could be altered in people with speech disfluency. This study aims to ascertain the possible correlation between two dopaminergic genes (SLC6A3 and DRD2) and disorder of speech(More)
This paper presents a novel multi-bit feedforward ΔΣAD modulator for low power and high signal-to-noise-and-distortion (SNDR) application. The integrators in the modulator are realized by ring amplifiers without static current. Multi-bit quantizer and analog adder in the feedforward modulator is realized by a passive-adder embedded successive(More)
A proof-of-concept Delta Sigma AD modulator using dynamic analog components is designed and fabricated in 90nm CMOS technology. The measurement results of an experimental prototype demonstrate the feasibility of the proposed switched-capacitor (SC) architecture to realize a 2nd-order Delta Sigma AD modulator with ring amplifier based integrators and dynamic(More)
This paper evaluates the first 15 months of the Ozone Mapping and Profiler Suite (OMPS) Sensor Data Record (SDR) acquired by the nadir sensors and processed by the National Oceanic and Atmospheric Administration Interface Data Processing Segment. The evaluation consists of an inter-comparison with a similar satellite instrument, an analysis using a(More)
