Abstract
The present disclosure describes a circuit having a current source and a load circuit coupled to the current source. The current source can include a transistor electrically coupled to a voltage supply and can be configured to generate a first current with a first current rate-of-change during a time interval, where the first current can be a cancellation current. In addition, the load circuit can be configured to generate a second current with a second current rate-of-change during the same time interval, where the second current can be a load current. The second current rate-of-change can be substantially an inverse of the first current rate-of-change. A power system can include a power management unit configured to generate a power supply voltage at an output, a current source and a load circuit electrically coupled to the output, and a control circuit controls the first current rate-of-change during the time interval.
