Majority logic gate with input paraelectric capacitors

A new class of logic gates are presented that use non-linear polar material. The logic gates include multi-input majority gates and threshold gates. Input signals in the form of analog, digital, or combination of them are driven to first terminals of non-ferroelectric capacitors. The second terminals of the non-ferroelectric capacitors are coupled to form a majority node. Majority function of the input signals occurs on this node. The majority node is then coupled to a first terminal of a capacitor comprising non-linear polar material. The second terminal of the capacitor provides the output of the logic gate, which can be driven by any suitable logic gate such as a buffer, inverter, NAND gate, NOR gate, etc. Any suitable logic or analog circuit can drive the output and inputs of the majority logic gate. As such, the majority gate of various embodiments can be combined with existing transistor technologies.

Method for using and forming low power ferroelectric based majority logic gate adder

An adder uses with first and second majority gates. For a 1-bit adder, output from a 3-input majority gate is inverted and input two times to a 5-input majority gate. Other inputs to the 5-input majority gate are the same as those of the 3-input majority gate. The output of the 5-input majority gate is a sum while the output of the 3-input majority gate is the carry. Multiple 1-bit adders are concatenated to form an N-bit adder. The input signals to the majority gates can be analog, digital, or a combination of them, which are driven to first terminals of non-ferroelectric capacitors. The second terminals of the non-ferroelectric capacitors are coupled to form a majority node. Majority function of the input signals occurs on this node. The majority node is then coupled to a first terminal of a non-linear polar capacitor. The second terminal of the capacitor provides the output of the logic gate.
