Performance Analysis of Novel Domino XNOR Gate in Sub 45nm CMOS Technology

In this paper, the authors propose three new versions of domino XNOR gate circuits. The proposed circuits adopt mixed N and P type transistor in the pull-down network. All performance parameters are measured at 25 deg. C and 110 deg. C. In first proposed circuit, it lowers the total leakage power by 8% to 12%, PDP is reduced by 6% to 9% and A.C noise margin is enhanced by 7% as compared to standard n-type XNOR gate. Second proposed circuit having multiple threshold voltage, lowers the total leakage power by 47% to 57%, PDP is reduced by 80% to 86% and A.C noise margin is enhanced by 33% as compared to standard n-type XNOR gate.
