Abstract
A circuit includes a magnetic logic unit including input terminals, output terminals, a field line, and magnetic tunnel junctions (MTJs). The field line electrically connects a first and a second input terminal, and is configured to generate a magnetic field based on an input to at least one of the first and the second input terminal. The input is based on an analog input to the circuit. Each MTJ is electrically connected to a first output terminal and a second output terminal, and is configured such that an output of at least one of the first and the second output terminal varies in response to a combined resistance of the MTJs. The resistance of each of the MTJs varies based on the magnetic field. The circuit is configured to generate an analog output based on the output of at least one of the first and the second output terminal.
