A wheel speed sensor interface receives an analog signal from a wheel speed sensor and converts the analog signal to a digital wheel speed sensor output signal. A detector circuit is configured to detect a transient occurring within a voltage source powering the wheel speed sensor, and compensate the digital wheel speed sensor output signal as a function of the detection of the transient so that it is an accurate representation of a wheel speed detected by the wheel speed sensor. The detector circuit includes a current mirror coupled to the voltage source, and outputs a compensation current to a current comparator of the wheel speed sensor interface.
