Static Component Interconnection Test Technology (SCITT) is a new XNOR circuit based technology that is used for board-level interconnection test. SCITT provides an easy test method using simple patterns and results in a high diagnostic resolution. The method is especially suited for SDRAM and other ‘complex memories’ but can be used for other devices as well. Very little overhead is required. ...

We present eight new designs for 1-bit full adder cell featuring hybrid CMOS logic style. These designs are based on a novel XOR-XNOR circuit that simultaneously produces XOR and XNOR full-swing outputs and outperforms its best counterpart showing 39% improvement in PDP. The new full-adder designs are also categorized in three main categories depending upon the implementation of the logic expre...

Digitally controlled oscillator (DCO) form the core of all digital phase locked loop (ADPLL).Nowadays portable batteries play a vital role in communication systems, hence low power circuits with reduced hardware are important. These criterions are satisfied by the proposed architecture. Different DCO designs with 3T NAND and 3T NOR gates as inverters proposed along with the result of 3T XOR and...

We have developed a new microelectromechanical logic device using the MEMS (Micro Electro Mechanical Systems) technology. This device consists simply of a single cantilever and two driving electrodes with two contact pads for electrostatic operation. Both exclusive NOR (XNOR) and exclusive OR (XOR) logic devices have been realized using this simple construction.

In this paper, a novel implementation of 8x8 Multiplier using 4-2 Compressors is presented; which produces quick results, especially for use in Digital Signal Processors and in Microprocessors. This multiplier uses a new partial-product reduction format which consecutively reduces the maximum output delay. The new design of multiplier requires less number of MOSFET’s compared to Wallace Tree Mu...

A directed logic circuit consisting of two silicon microring resonators which can perform XOR and XNOR operations has been proposed. These two operations are evaluated as the optical signal is directed along the circuit, and the results appear at some specific output ports of the circuit. A potential advantage of this new logical paradigm is that it has markedly less state delay than traditiona...
