Abstract:
Methods and apparatus for current sensing and error correction in a switched-mode power supply composed of a high-side transistor coupled to a low-side transistor are described. One example method generally includes capturing a current associated with the low-side transistor at a first time corresponding to the low-side transistor turning off; capturing a current associated with the high-side transistor at a second time corresponding to a first delay after the high-side transistor turns on; capturing the current associated with the high-side transistor at a third time corresponding to the high-side transistor turning off; and applying a first correction current to a current-summing node of the current-sensing circuit for a first interval based on the first delay, wherein the first correction current is based on the captured current associated with the low-side transistor at the first time and on the captured current associated with the high-side transistor at the second time.

Claim (Index 18):
The current-sensing circuit of  claim 17 , wherein the shunt resistor has a resistance and wherein the first voltage-to-current converter is configured to have a transconductance inversely proportional to the resistance of the shunt resistor.
