A VLSI implementation of a CMOS circuit realizing a Discrete Wave Transform ( DWT) for Daubecchie's 6 using a novel realization of Quadrature Mirror Filter [QMF] is presented. The new design of the DWT system which is based on a new Finite Impulse Response filter FIR requires less Si area to be implemented, since the FIR filter is implemented using mixed parallel / sequential architecture resulting in reducing the number of binary multipliers used which are the major bottle neck governing the performance of the DSP processing. Consequently, it results in a much faster system. Moreover, the use of parallel multipliers results in less power dissipation.","PeriodicalId":403026,"journal":{"name":"Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems.

Wavelet compression schemes demand a rate control algorithm for real-time video communication systems. Furthermore, 3D wavelet compression schemes require, a group of frames (GOF) to process the third dimension of wavelet coefficients. The GOF thus produces an inherent delay in the transmission of real-time video. Also, for real-time video transfer, the frame acquisition rate of the server, and the display frame rate of the client must be equal. These factors must be taken in to consideration when developing a control algorithm to supply a constant frame rate from server to client. Our solution to this rate control problem is comprised of a leaky bucket algorithm used in both the client and server sides.","PeriodicalId":403026,"journal":{"name":"Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems.

The design methodologies include a careful decomposition between the digital and analog sections, as well as between the individual analog blocks, which decreases time-to-market and enhances design reuse.

The PZT structure enables the actuation and the sensing of the ultrasonic waves. The transducer was tested for impedance characteristics, fundamental resonance modes. This work shows the potential of thin film PZT for ultrasonic imaging transducers. The novel microfabrication process minimizes the size of the transducers, the spacing between the individual devices while minimizing the cross talk. The use of the PZT allows for maximum sensitivity. A two-dimensional array, like the one demonstrated in this work can be potentially used for coronary artery imaging.","PeriodicalId":403026,"journal":{"name":"Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems.

To process/store/analyze the signals acquired from these medical sensors, analog/digital systems are used to provide data fusion and information extraction. These biomedical smart sensors cover the hybrid domains of mixed-technology (electrical, mechanical, optical, thermal, biochemical) and mixed-concept (electrical, control, digital signal processing).
