A device for averaging a sensed current includes a sampling circuit that samples at least two sampling points of each cycle of a front-end alternating current (AC) sensed signal. The two sampling points is substantially symmetrical with respect to a midpoint of each respective cycle of the front-end AC sensed signal. The device also includes a timing circuit that controls a timing of the sampling circuit to sample the front-end AC sensed signal on the at least two sampling points based on a timing signal generated by the timing circuit. The device further includes an averaging circuit that averages the two sampling points for a given cycle of the front-end AC sensed signal to produce an average sensed current.
