Abstract: A set of AC logic circuits that can be powered by AC signals for saving power in microchips. The logic circuits use the relative phases of different AC signals, and a load capacitance to perform digital logic operations in different phases of the AC signals. One phase is used to charge the load capacitor and another phase is used to discharge the capacitor; some of the phases may be just the hold phases to hold the values of the signals. The charging and discharging phases are enabled depending on the input signals and the corresponding expected output of the digital function to be implemented. The circuits can be used in wirelessly powered devices with small number of gates to save power losses associated with the DC rectification. They can be used to perform any kind of combinational gates like NAND, NOR, XOR and also sequential circuits like D Flip flop.
