Abstract
A speed sensor device includes sensing elements to sense an angle of a moving target and to generate sine and cosine signals in response thereto; a signal condition circuit to process the sine and cosine signals, the processed sine and cosine signals having a phase lag introduced by the signal condition circuit; and a phase lead filter to receive the processed sine and cosine signals and to reduce the phase lag in the processed sine and cosine signals.
