We propose a forming method of hydrogel-based cell sheets for regenerating three dimensional lobule-mimetic constructions. Accumulating the cells are conventional methods of three dimensional designs. In this study, we have designed a cell sheet chip to form a poly (ethylene glycol) diacrylate (PEGDA)-based cell sheet by two methods. First method is to pattern cells by DEP force for mimicking the...
A low-power, high-speed full adder (FA), abbreviated as LPHS-FA, is presented as an elegant way to reduce circuit complexity and improve the performance thereof. Employing as few as 15 MOSFETs in total, an LPHS-FA requires 60??73% fewer transistors than other existing FAs with drivability. For validation purpose, HSPICE simulations are conducted on all the proposed and referenced FAs based on the...
Signal processing circuits are very useful elements in fuzzy logic, artificial neural network, and image application. In image processing, median filter is adopted to remove pulse noise. In the paper, a real-time CMOS analog median circuit is proposed. Based on current-mirror, current comparison, and some digital logics, a new analog median filter with high-speed low chip area is achieved. By using...
