  • Circuit for adjusting reference voltage using fuse trimming
    Patent number: 7589581
    Abstract: A binary bidirectional trimming circuit is disclosed. The trimming circuit includes: a first resistor set having 4 resistors in parallel connected and a first fuse bridged two ends thereto provide one trimming step; a second resistor set having 2 resistors in series connected and a second fuse bridged two ends thereto provide eight trimming steps; a third resistor set having 2 resistors in parallel connected and a third fuse bridged two ends thereto provide two trimming steps; a fourth resistor set having 1 resistor and a fourth fuse bridged two ends thereto provide four trimming steps; a first loading resistor; and a second loading resistor. The first resistor set, second resistor set, first loading resistor, third resistor set, the fourth resistor set, and the second loading resistor are in series connected.
