Abstract
A sample-and-hold circuit is described which includes a network of thin-film elements in a bridge configuration. Each of the thin-film elements exhibits giant magnetoresistance. The circuit also includes a plurality of conductors inductively coupled to each of the thin-film elements for applying magnetic fields thereto. The circuit is operable using the plurality of conductors to sample and store a value corresponding to an input signal.
