Quantum‐dot Cellular Automata (QCA) lead to fundamental changes in nanoscale technology. It promises small area, low power, & high‐speed structures for digital circuit design. This paper presents efficient low power structures of reversible multiplexer & demultiplexer (RMD) modules based on the QCA technology. The simulation result shows that the proposed RMD module has utilized less area...
The use of near infra red (NIR) photoacoustic spectroscopy (PAS) for continuous non-invasive glucose measurement is outlined in the paper. A photoacoustic (PA) measurement apparatus was constructed and PA measurements were made on glucose solutions at multiple NIR excitation wavelengths. A variety of time and frequency domain features, including amplitude and area based features, were extracted from...
This paper proposes low cost reconfigurable embedded back-end architecture for high speed data acquisition, noise cleaning and real time display for a photoacoustic based continuous noninvasive blood glucose monitoring system to combat deadly Diabetes. The signal to noise ratio (SNR) improvement of repeated photoacoustic signal is accomplished by the coherent averaging with trigger unit added as intellectual...
This paper presents a method for improvement in SNR and resolution of photo acoustic (PA) signal using Golay coded excitation for a non-invasive and continuous glucose monitoring. The simulation results with a Golay code of length 4 has been shown, which gives a coding gain of 9.03 dB in comparison to regular pulse triggering. Furthermore, Golay coded excitation results in better resolution of PA...
