Abstract :
Super cut-off devices with sub-60mV/decade subthreshold swings have recently been demonstrated and being extensively studied. This paper presents a feasibility analysis of such tunneling devices for ultralow power subthreshold logic. Analysis shows that this device can deliver 800times higher performance (@iso-IOFF) compared to a MOSFET. The possible use of this device as a sleep transistor in conjunction with the regular Si MOSFET shows 2000times average improvement in leakage power compared to Si MOSFETs
