Design of a 4 bit Arithmetic and Logical unit with Low Power and High Speed

In this presented work we designed the 4- bit Arithmetic & Logical Unit (ALU) by using different modules. The Various modules are AND gate OR with six transistors, While XOR is both eight transistors transistors. transistor module gives optimized results. Another one four multiplexer implemented Pass logic (PTL) style. full adder 18 through PTL Here because of style number count such that constraints get By AND, OR, XOR, 4X1 MUX and reduced ALU. With ALU 4 compared outcomes conventional design so proposed has count, area, power, delay power product (PDP). Simulations verified 130nm mentor graphics tool.
