Abstract
Systems and methods for sense resistors are disclosed. In one aspect, an integrated sense resistor includes a plurality of first metal bumps alternating with a plurality of second metal bumps in at least a first lateral direction and a plurality of thin film resistors each disposed between and electrically connected to a pair of adjacent ones of first and second metal bumps. The integrated sense resistor can be configured for sensing a voltage developed by current flowing across the integrated sense resistor for determining a value of the current.
Claims17
An integrated sense resistor, comprising:
- a plurality of first metal bumps alternating with a plurality of second metal bumps in a first lateral direction and further in a second lateral direction orthogonal to the first lateral direction, such that the plurality of first metal bumps and the plurality of second metal bumps are arranged in a checkerboard pattern;
- and
- a plurality of thin film resistors each disposed between and electrically connected to a pair of adjacent ones of the plurality of first metal bumps and the plurality of second metal bumps,
- wherein the integrated sense resistor is configured for sensing a voltage developed by current flowing across the integrated sense resistor for determining a value of the current.
A system-in-package (SiP), comprising:
- a board substrate;
- and
- an integrated sense resistor comprising:
