Abstract
An electronic circuit dynamically compensates a sensor output signal subject to varying conditions. In particular, the circuitry dynamically determines the DC offset level of an incoming sensor analog output signal. The DC amplitude or offset level varies as a result of changing conditions, such as speed, airgap, alignment and temperature. The circuitry compares the DC offset level with the original sensor analog output signal by way of a comparator to provide a digital output signal with a zero DC offset, which compensates for the varying conditions.
