Abstract: An example embodiment includes an idle state detection circuit. The idle state detection circuit includes a bias current loop, a rectifying circuit loop, a voltage translating loop, and a filter circuit. The bias current loop provides a rectifying diode a forward current such that the rectifying diode detects an alternating current (AC) signal received from a transmitter via one or more transmission nodes.

The voltage translating loop converts the differential peak to peak amplitude information stored at the first capacitor to a single-end voltage signal across a first resistor that is electrically coupled to the cathode side of the rectifying diode. The filter circuit filters an AC component of the single-end voltage signal.
