Abstract
In accordance with embodiments of the present disclosure, a system may include a main integrated circuit (IC) comprising current measurement circuitry, an auxiliary current sense resistor coupled to the main IC, and an auxiliary pair of Kelvin sense resistors coupled between the auxiliary current sense resistor and the current measurement circuitry. The main IC may further comprise current injection circuitry configured to inject a known sink current which is split between a main current in a first path and an auxiliary current in a second path comprising the auxiliary current sense resistor.
