In this paper, a compact SPICE model of flexible transition metal dichalcogenide field-effect transistors (TMDFETs) is developed with considering effects when scaling the transistor size down to the 10-nm technology node. The model supports different transistor design parameters such as width, length, oxide thickness, and various channel materials, as well as the applied strain, which enables the evaluation of transistor- and circuit-level behavior under process variation and different levels of bending. Extensive device-level simulations are performed using this model, and TMDFETs are compared with different Si- and graphene-based devices. We performed circuit-level simulations, and reported the delay, power, and EDP of the benchmark circuits. Effects from process variation are also evaluated. These cross-technology studies show that TMDFET's power is comparable to the low-power multigate devices (about 0.4% lower). The delay and EDP are 60% and 2.3% higher than the graphene-based devices, respectively. The developed compact model would enable SPICE-level circuit simulation for early assessment, design, and evaluation of futuristic TMDFET-based flexible circuits targeting advanced technology nodes.
