44 results about "Shunt (electrical)" patented technology

In electronics, a shunt is a device which creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb 'to shunt' meaning to turn away or follow a different path.

A system and method for implementing an electronic circuit for protecting electronic components from ESD. A PCB or IC may include an electrostatic discharge protection layer having a first and second conductive layer separated by a semi-conductive dielectric layer. Further, the PCB / IC may include a protected node coupled to the first conductive layer and a current-shunt node electrically coupled to the second conductive layer, such that a signal at the protected node that is below a threshold magnitude propagates through the protected node in a normal operating path and a signal at the protected node that exceeds a threshold magnitude is diverted to the semi-conductive dielectric layer to the current-shunt node in a current-shunt path. In this manner, existing layers of a PCB / IC may be used for both ESD protection and other functions, such as ground planes or battery plane by isolating the specific sections of the layer for its intended use.

Three dimensional dynamically shielded high quality factor (Q) BEOL metal elements, such as inductor elements, are disclosed. Three dimensional shielding structures for the BEOL elements reduce or eliminate parasitic substrate capacitive coupling between the BEOL element and the conductive substrate, and parasitic shunt capacitance coupling between different adjacent shunt sections of the BEOL element. The reduction or elimination of the parasitic capacitive components provides high Q BEOL metal elements such as inductor elements. The three dimensional shield structure includes a lower shield surface having a width greater than the width of the BEOL element, and opposed side shield surfaces which extend upwardly from opposite side edges of the lower shield surface, such that the three dimensional shield element forms a U shaped shield around the BEOL element. The three dimensional shield element is dynamically driven to the same electrical potential as the BEOL element, to substantially eliminate the metal element's parasitic capacitances.

Mg discontinuous insertion layer for improving mt j shunt

A MTJ is disclosed with a discontinuous Mg or Mg alloy layer having a thickness from 1 to 3 Angstroms between a free layer and a capping layer in a bottom spin valve configuration. It is believed the discontinuous Mg layer serves to block conductive material in the capping layer from diffusing through the free layer and into the tunnel barrier layer thereby preventing the formation of conductive channels that function as electrical shunts within the insulation matrix of the tunnel barrier. As a result, the “low tail” percentage in a plot of magnetoresistive ratio vs Rp is minimized which means the number of high performance MTJ elements in a MTJ array is significantly increased, especially when a high temperature anneal is included in the MTJ fabrication process. The discontinuous layer is formed by a low power physical vapor deposition process.
