Abstract
A method for detecting quiescent current in an integrated circuit is provided that includes detecting a magnetic field generated by the quiescent current and in response generating a magnetic field signal that is indicative of the detected magnetic field. The magnetic field signal is then amplified and converted into a differential voltage signal. The differential voltage signal is then converted into a digital format.
