|
Exclusive NOR (XNOR) gates are very important in electronics department. This is widely used in digital circuits. This paper proposes the novel design of 2T XNOR gate using pass transistor logic. The proposed circuit has the minimum transistor count and there is no complementary input signal is used. This design has been compared and analyzed with earlier designed XNOR gates and a significant improvement in silicon area and power-delay product has been obtained against previous 3T XNOR gate. Instead of cascading two two-input XNOR gates, in this paper we design a new structure of 4-bit comparator on the transistor level. The performance has been investigated using 0.18μm Technology and evaluated by the comparison of the simulation result obtain from TSPICE. |
