1. A filter circuit for use with a system configured to be coupled with an electrical load, the filter circuit comprising:
a first filter configured to receive a first voltage and provide an output voltage, the output voltage being the first voltage after filtering by the first filter; and
a controller configured to:
receive a first current, the first current being dependent on a load current;
based on the first current received, detect a load transient by detecting a transient in the load current; and
adjust a bandwidth of the first filter in response to the load transient detected.
