Abstract
An apparatus includes an circuit and a latching micromagnetic switch that controls energy flow through the circuit. The latching micromagnetic switch includes a cantilever, a permanent magnet, and a coil configured to latch the latching micromagnetic switch in one of two positions each time energy passes through the coil. The electrical device and the latching micromagnetic switch can be integrated on a same substrate. Otherwise, the electrical device and the latching micromagnetic switch can be located on separate substrates and coupled together. The circuit can be a transistor or an array of transistors connected in parallel. If the circuit is an array of transistors, there can be an array of the switches, where each one of the switches is coupled to a corresponding one of the transistors. The switches are coupled to at least one of a source, drain, or gate of the corresponding transistor.
