This paper proposes a low-power variation - immune dual-threshold voltage CNFET-based 7T SRAM cell. The proposed CNFET-based 7T SRAM cell offers ~1.2× improvement in standby power, ~1.3× improvement in read delay, ~1.1× improvement in write delay. It offers tighter spread in write access time (1.4× @ OEP (optimum energy point) and 1.2× @ VDD=1 V). It features 56.3% improvement in hold static noise...
Subthreshold circuits are an ideal choice for ultra low power, moderate throughput applications. In subthreshold region to meet the ultra-low power requirement of energy constrained devices, supply voltage less than the threshold voltage is applied. At same frequency, subthreshold circuits show orders of magnitude power saving over superthreshold circuits. In subthreshold operating region, minute...
Field programmable gate array (FPGA) consumes significant dynamic and static power consumption due to the presence of additional logic for flexibility compared to application specific integrated circuits (ASICs). The cost of ASICs is rising exponentially in deep submicron and hence it is important to investigate ways of reducing FPGA power consumption so that they can also be employed in place of...
Carbon nanotube field effect transistors (CNFETs) are already competitive in some respects with state-of-art silicon transistors, and are promising candidates for future nano-electronic devices. The ability of CNFET for using high K-dielectric provides high insulator capacitance which improves the gate control and also lowers gate leakage. This paper proposes new energy efficient CNFETs based drivers...
