Abstract
A DC-DC converter is disclosed. The DC-DC converter includes a sensing circuit having a first path to sense an output current of the DC/DC converter. A reference circuit generates a reference current to flow along a second path. The reference current is for comparison to the output current. A noise injection circuit couples to the second path and includes a replica circuit of the sensing circuit to sense the reference current. A differential amplifier rejects a common mode noise between the first path and the second path.
