Abstract
An electrical device is disclosed, comprising electrical components forming an electrical circuit, with a trim circuit comprising two or more trim cells providing selectively removable resistances between first and second nodes in the electrical circuit. The resistance between the nodes is trimmed incrementally by application of trim signals to a single pair of terminals or pads on the device, allowing post-packaging trimming. Methods are also disclosed for selective removal of resistance between first and second nodes in a packaged electrical device.
