ULTRA-LOW POWER VOLTAGE REFERENCE CIRCUIT UTILIZING A THRESHOLD VOLTAGE DIFFERENCE BETWEEN TWO CNFETS

Abstract
This paper proposes a voltage reference circuit that exploits sub-threshold conduction and threshold voltage difference between two carbon nanotube field effect transistors (CNFETs) to achieve ultra-low power consumption. The circuit produces a reference voltage of 203mV at 0.5V supply voltage, consumes only 3.42pW power and exhibits excellent temperature and power supply independence. The robustness of the proposed circuit for variations in carbon nanotube (CNT) diameter and inter CNT pitch variations is also presented with Monte Carlo simulations.
