  • Low-power digital logic using a Boolean logic switched inductor-capacitor (SLC) circuit
    Patent number: 9438233
    Abstract: A low-power digital logic architecture exhibits the same logic and voltage level behavior as standard digital logic. A logic switch and a pair of unidirectional switches are used to control the direction of charge flow in a switched-inductor capacitor (SLC) circuit, allowing the inductor to pull charge back-and-forth from one side of the load capacitor to the other to both switch the logical state at the top of the capacitor and to recycle and store the charge in the capacitor itself.
