As the MOSFET continues to shrink rapidly, emerging physical phenomena, such as ballistic transport, have to be considered in the modelling and simulation of ultra-scaled devices. Future Double-Gate MOSFETs, designed with channel lengths in the decananometer scale, are expected to be more ballistic or quasi-ballistic than diffusive. At this level of miniaturisation is essential to directly evaluate the impact of ballistic and quasi-ballistic transport at circuit level through simulation of several circuit demonstrators. In this work we demonstrate the feasibility of a simulation study of ballistic/quasi-ballistic transport at circuit level and we show the impact this advanced transport on the commutation of CMOS inverter and the oscillation frequency of ring oscillator.
