Abstract:
The present invention is directed to data communication. According to a specific embodiment, the present invention provides technique for loss of signal detection. A loss-of-signal detection (LOSD) device determines an analog signal indicating signal strength by subtracting a threshold offset voltage from an incoming signal. The analog signal is then processed by a switch network of an output stage circuit, which provides a digital output of loss of signal indication at a low frequency (relative to the incoming signal frequency). There are other embodiments as well.

Claim (Index 1):
A loss-of-signal detection device comprising:\n a first terminal configured to receive a first input signal, the first input signal being characterized by a first frequency; a first hysteresis voltage source configured to apply a first predetermined hysteresis voltage to the first input signal to provide a first adjusted signal; a bias voltage source being configured to provide a bias voltage; a first transistor comprising a first gate and a first source, the first adjusted signal being coupled to the first gate; a second transistor comprising a second gate, a second source, and a first drain, the second gate being coupled to the bias voltage, the second source being coupled to the first source; and an output module comprising a switch network and a latch, the switch network being configured to generate an intermediate signal using a strength indicator signal received from the first drain of the second transistor and an offset associated at least with the first transistor, the latch being configured to generate a loss-of-signal indicator based on the intermediate signal at a second frequency, the second frequency being lower than the first frequency; wherein the switch network operates in a first phase and a second phase, the switching network being configured to determine a common offset voltage during the first phase, the switching network being configure to generate the intermediate signal during the second phase.
