For many years CMOS logic gates have been preferred mainly for their rail-to-rail swings, strong on/off states, robust operation, large noise margins and low static power. However, one of the main drawbacks of CMOS gates is the need to implement complementary computation networks: the NMOS based pulldown network (PDN) and the pull-up (PUN) PMOS network. Both networks (depending on the logic function of gate) consist of a few stacked transistors. The number of stacked transistors increases with the increase of the Fan-In of the gate, which usually requires upsizing these transistors to improve performance and noise margins. This issue is even more crucial in gates such as NORs, where low mobility stacked PMOS transistors significantly limit the performance of the gate and require large transistors, thus increasing the intrinsic capacitance and power dissipation of the gate. An example of a conventional CMOS NOR3 gate is shown in Fig. 1(a).","PeriodicalId":333587,"journal":{"name":"2017 IEEE SOI-3D-Subthreshold Microelectronics Technology Unified Conference (S3S)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114194791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Power Analysis Attacks (PAAs) [1] exploit the information leakage from the device's power consumption (typically measured on the supply and/or ground pins). Digital circuits consume dynamic switching energy when data propagate through the logic in each new calculation (e.g. new clock cycle). The average power dissipation of a design can be expressed by: Ptot(t) = α · (Pd(t) + Ppvt(t)) (1) where α is the activity factor (the probability that the gate will switch) and depends on the probability distribution of the inputs to the combinatorial logic. This induces a linear relationship between the power and the processed data [2]. Pd is the deterministic power dissipated by the switching of the gate, including any parasitic and intrinsic capacitances, and hence can be evaluated prior to manufacturing. Ppvt is the change in expected power consumption due to nondeterministic parameters such as process variations, mismatch, temperature, etc. In this manuscript, we describe the design of logic gates that induce data-independent (constant) α and Pd.","PeriodicalId":333587,"journal":{"name":"2017 IEEE SOI-3D-Subthreshold Microelectronics Technology Unified Conference (S3S)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133466945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, M3D concept can have additional benefit by integrating two or more different materials [2].
