Quantum-dot Cellular Automata (QCA) is an emerging and promising technology that provides significant improvements over CMOS. Recently QCA has been advocated as an applicant for implementing reversible circuits. However QCA, like other Nanotechnologies, suffers from a high fault rate. The main purpose of this paper is to develop a fault tolerant model of QCA circuits by redundancy in hardware a...

Realization of a novel single-resistance-controlled oscillator, employing an active element and all grounded passive elements, is the purpose of this manuscript. With requirements for completing the design being only a single Voltage Differencing Current Conveyor and four grounded passive components, it is also a preferable choice for integrated circuit implementation. The designed circuit has ...

this paper presents a design of an uwb downconversion integrated cmos resistive ring mixer with linear voltage regulator (lvr), to supply required biasing voltages for the mixer section. the designed mixer circuit has been optimized for using in heart rate extraction system with microwave doppler radar at 2.4ghz frequency. this mixer needs 2 dc bias voltages equal to 0.5 and 1 volts for its bes...

It's not surprisingly when entering this site to get the book. One of the popular books now is the gallium arsenide digital integrated circuit design. You may be confused because you can't find the book in the book store around your city. Commonly, the popular book will be sold quickly. And when you have found the store to buy the book, it will be so hurt when you run out of it. This is why, se...

In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...

Is your perfusion circuit the best that it can be? With continued decreasing reimbursements, reducing the costs associated with your perfusion circuit can have significant positive impact on the overall cost of your cardiac surgery service. Perfusion circuits are inherently deleterious. Hemodilutional and inflammatory influences translate into prolonged ventilator times, longer ICU and hospital...

We present two new ways to implement ordinary programs with logic gates. One, like imperative programs, has an associated memory to store state; the other, like functional programs, passes the state from one component to the next. Application-specific circuit design can be done more effectively by using a standard programming language to describe the function that a circuit is intended to perfo...
