Abstract:
A trim circuit for providing a selectively removable resistance between first and second nodes in an electrical device, comprising:a resistor comprising a resistor body and first and second ends and providing an electrical resistance between the first and second nodes, the first end of the resistor being connected to the first node and to a first pad in the electrical device; and a diode formed in the resistor body and comprising an anode, a cathode, and a conductive portion connected to one of the anode and the cathode, the anode being connected to the second end of the resistor, and the cathode being connected to a second pad in the electrical device; wherein the conductive portion of the diode connects the first and second ends of the resistor so as to remove resistance between the first and second nodes after a trim voltage is applied across the first and second pads.
