A New Adiabatic Logic Circuit for RF Energy Harvesting

Wireless-powered energy harvesting has been employed in various Internet of Things (IoT) devices. Optimizing low power consumption and ensuring the security of confidential information have become critical points. In this paper, the proposed circuit presents a stable power consumption and supply current in various input transition logics. The current passes in each input transition logic at the function block have been uniformized to reduce the current and energy fluctuation. The different power clock frequencies and various load capacitances have been evaluated. The current and energy fluctuation has been reduced significantly from the conventional adiabatic logic circuit. The bipolar sinusoidal from an RF signal can be converted to unipolar by a diode-connected PMOS transistor for supplying energy to an adiabatic circuit.
