| Summary: | In this paper, a compact and complementary logic implementation is proposed for antiferromagnet field-effect transistor (AFMFET) devices. The implementation enables a complete set of Boolean operations based on complementary logic as well as majority-gate logic. The impacts of several key device-level design parameters are investigated, such as the channel resistance and critical switching voltage, and their optimal values that minimize the overall energy-delay product (EDP) of a 32-bit arithmetic logic unit are quantified. In addition, it is shown that one can potentially take advantage of the large domain size of some AFM materials such as chromium and build a compact majority-gate-based logic. The potential performance benefits of the majority-gate-based logic are also quantified. Compared to the conventional CMOS logic circuit, the one with AFMFET devices using majority gates can potentially achieve 10× improvement in terms of the EDP.
