Devices and methods are provided for current sampling and processing associated with, for example, an inverter for an electric vehicle to improve the performance of the inverter. By providing initial parameters for the devices and methods as well as providing estimates of some parameters, the devices and methods can reduce a delay in the time required to perform the sampling and processing of the current. Specifically, parameters for the next beat of a cycle are estimated in the previous beat to complete processing of the current faster, which reduces the delay time. This reduction in delay time increases an output bandwidth of the current loop, i.e., a maximum frequency of an alternating current that can be output by the current loop without attenuation, which improves the performance of the inverter.
