Low-voltage and Low-power Systems using Common Gate Comparator

Abstract

Low power design is needed to lower the power in high-end systems. The development of battery-free, maintenance-free Internet of Things devices has drawn attention to energy harvesting. The MTCMOS approach should be used from the system level down to the process level in order to precisely optimize power dissipation using low power methodology in digital systems. This paper proposes low-voltage and low-power systems using common gate comparator. Through a MOS switch, the suggested method removes undesirable ripple and noise voltages, with reference to the input and output voltages. The current that flows through the comparator can be used to adjust its voltages. MTCMOS power gating is used to create systems with extremely low power consumption in order to accomplish highly effective power management. For portable IT applications, where leakage power consumption is crucial to battery life, the significant reduction in power consumption using MTCMOS may be advantageous. The comparator is simulated in 45nm technology using Cadence tool to achieve power consumption of 413. 23uW.
