Rajveer Singh

Abstract


In present work another XOR gate utilizing three transistors has been proposed. Configuration demonstrates sufficient output rationale levels with commotion edge of 2V with 3.3V information signals. XNOR rationale, got with expansion of inverter shows enhanced clamor edge of 3.2V. Another plan for single piece full adder has been executed utilizing proposed XOR/XNOR gates and transmission gate multiplexer. Full adder planned with 14 transistors demonstrates control scattering of 650.6 µW and most extreme output postpone 0.11ns. Proposed adder circuit demonstrates satisfactory commotion edge of 3.2 V for (Sum output) and 2.2V for Cout (Carry output) with supply voltage of 3.3V. Circuit functions admirably with lessened supply voltage and reproductions have been completed up to 1.8V supply voltage. Reenactments are performed by utilizing SPICE in view of TSMC 0.35µm CMOS innovation. Power consumption of proposed full adders has been contrasted and before reported circuits and proposed circuit's shows better execution regarding power utilizations and transistor number.
