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 a first analog input to the circuit. Each MTJ is electrically connected to a first 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 the MTJs varies based on the magnetic field. The circuit is configured to mix the first analog input and a second analog input to generate an analog output based on the output of the second output terminal.
