Abstract: A complementary logic technology is disclosed whereby a logic gate comprises at least two metal-to-insulator transition (MIT) elements and at least two thermoelectric elements, each MIT element being thermally coupled to a corresponding thermoelectric element. In logic gates, each electric signal at an input terminal of a logic gate is first converted into two complementary thermal signals, and these thermal signals in turn determine the status of the output terminal of the logic gate, thereby generating an electrical output signal inverse to the electrical input signal or an output signal which is a Boolean operation on input signals. The parallel connection(s) of thermoelectric elements of the logic gate is used to create corresponding thermal signals for each electrical input signal. The MIT elements of the logic gate are then arranged to, in response to the associated thermal signals, execute a Boolean operation.
