We describe a 14-bit 2.5GS/s non-interleaved pipelined ADC that relies on correlation-based background calibrations to correct the inter-stage gain, settling (dynamic), kick-back and memory errors. A new technique is employed to inject a large dither signal on the input to dither the non-linear kick-back on the ADC driver, and another large dither signal is injected to dither any residual non-linearity...
In this paper, we propose a theoretical physical lumped parameter model for the mixing process in plasticizing self-wiping twin screw extruders using a combination of statistical techniques and mechanistic modelling. The model describes the response of the extruder to input signals of feed rate and screw speed in the time domain via residence time density distribution (RTD). It is shown that the RTD...
The characteristics of powder coatings manufactured through a novel processing technique based on nonisothermal Nlow‐induced phase inversion granulation enhanced by fluid injection to promote phase inversion and particle formation from melt state is summarized. Experiments were carried out in a purpose‐built granulator, which operates in a parallel disk rotor‐stator arrangement, so that the mechanism...
Ionotropic glutamate receptors (iGluRs), a family of ligand-gated ion channels, are responsible for the majority of fast excitatory neurotransmission in the central nervous system. Within this family, different members serve distinct roles at glutamatergic synapses. Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors mediate fast depolarization while N-methyl-D-aspartate (NMDA) receptors...
