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.

Transpinnor-based sample-and-hold circuit and applications

An electromechanical structure such as a MEMS resonator formed in the surface of a semiconductor body. A flexible beam containing a conductive plate is integrally formed in a cavity in the surface of a semiconductor body. A second conductive plate is parallel to the first along a sidewall of the cavity. A voltage applied across the first and second conductive plates forces the flexible beam to vibrate horizontally. A cap layer seals the cavity and maintains a vacuum in the cavity. The structure is smaller than the wavelength of the RF signal generated therefrom and, therefore, virtually shielded.

Vacuum sealed RF/microwave microresonator

Vertical field emission devices are described with very small cathode to anode separations. Preferred cathodes have sharp edge emitters extending, outward perpendicular to the surface of the underlying substrate. These sharp edge emitters are produced within planar photolithography by coating sacrificial conformal walls and anisotropic etching. Microencapsulation is used to produce a sealed cavity at low pressure which includes the space between the anode and cathode. The field emission components can be adapted for the production of light emitting, field emission diodes. The individual cathode emitters can be integrated with solid state components on the substrate with each cathode being independently addressable. Arrays of closely packed light emitting, field emission diodes of the present invention are particularly suitable for use in displays. These displays would be useful for flat-panel computer displays and high definition television.
