VERTICAL METAL SENSING METHOD FOR DC-DC CONVERTER

In a DC-DC converter, a layout is designed to enable utilization the conductive trace connecting the converter output node to an output bump at which the load is attached as a sense resistor. The layout forces the output current down into lower metallization levels of an interconnect layer reaching...

Zusammenfassung:	In a DC-DC converter, a layout is designed to enable utilization the conductive trace connecting the converter output node to an output bump at which the load is attached as a sense resistor. The layout forces the output current down into lower metallization levels of an interconnect layer reaching the converter output node before the output current flows up into this conductive trace and out through the output bump. The conductive trace includes resistive pillars connected in parallel or series between the lower metallization levels and a top metallization layer of the conductive trace, with these resistive pillars being substantially greater in resistance than the lower metallization levels and the top metallization layer of the conductive trace.
