Abstract
A trimming circuit is configured to carry out a trimming operation on a device portion of an integrated circuit device. The trimming circuit includes: shunt fuses wherein each shunt fuse is coupled in parallel to a trimming resistance, further resistances wherein each further resistance is coupled in parallel to a respective shunt fuse. The circuit is configured to allow the flow of the trimming current when the respective shunt fuse is burnt during the trimming operation.
