The leakage current characteristics of wide dual Vt domino OR gates is studied and gate-level models for estimating sub-threshold leakage and gate leakage current with two different sleep states are developed to determine the optimal sleep state. Results demonstrate that the developed models are robust and exhibit maximum error of 4% with respect to device-level BSIM4 models based HSPICE simulations. Furthermore, PVT variation aware leakage current characteristics of domino OR gates is analyzed and the optimal sleep state is obtained.
