Design a Nebulizer and its Implementation on FPGA using HDL

VLSI systems plays important role among all other system. A nebulizer is a drug delivery device used to administer medication in the form of a mist inhaled into the lungs. The application of spray device to treat respiratory disease has been effective for long time. Asthma and chronic obstructive pulmonary disease are widely prevalent in industries part of the world. The principle of ultrasonic nebulizers is based on the vibrations of a piezoelectric crystal driven by an alternating electrical field. These periodic vibrations are characterized by their frequency, their amplitude, and their intensity, which corresponds to the energy transmitted per surface unit. When the vibration intensity is sufficient, cavitation occurs, and droplets are generated. For a given nebulizer, the vibration frequency of the piezoelectric crystal is fixed, often in the range 1 to 2.5MHzThis is different way to design nebulizer on FPGA spartan3E kit using Xilinx tool using Verilog HDL. We have tried interface ADC device.
