Zusammenfassung:	The present disclosure describes an apparatus, system, and method for cancelling noise (e.g., power supply noise). For example, the apparatus can include a load circuit, a sense resistor, and a current compensation circuit. The load circuit is configured to draw a first current (e.g., a load current). The sense resistor is configured to provide a voltage based on the first current. The current compensation circuit is configured to generate a second current (e.g., a compensation current) based on the voltage. A sum of the first current and the second current can be substantially constant.
