A new design 6T Full Adder Circuit using Novel 2T XNOR Gates

چکیده
Exclusive-NOR (XNOR) gates are important in digital circuits. This paper proposes the novel design of 2T XNOR gate using pass transistor logic. The proposed circuit utilizes the least number of transistors and no complementary input signal is used. The design has been compared with earlier designed XNOR gates and a significant improvement in silicon area and power-delay product has been obtained against 3T XNOR gate. In this paper we designed a new 6 transistor full adder using the proposed two-transistor XNOR gate. The performance has been investigated using 0.18μm Technology and evaluated by the comparison of the simulation result obtain from TSPICE.

متن کاملThe Influence of Silicon Area on the Performance of the Full Adders
Recently, the influence of the silicon area on the delay time, power dissipation and the leakage current is a crucial issue when designing a full adder circuit. In this paper, an efficient full adder design referred to as 10-T is proposed. The new design utilized the use of XNOR gates instead of XOR in the full adder implementation and, as a result, the delay time and power dissipation are sign...
