  • Power- and area-efficient clock detector
    Patent number: 10727820
    Abstract: A clock detector includes a first detector circuit, a second detector circuit, and a toggle detector circuit. The first detector circuit is for activating a first detect signal in response to detecting that a clock signal that toggles between first and second logic states when present is stuck in the first logic state, and keeping the first detect signal inactive otherwise. The second detector circuit is for providing a second detect signal in response to detecting that the clock signal is stuck in the second logic state, and keeping the second detect signal inactive otherwise. The toggle detector circuit is for activating a toggle detect signal in response to both the first detect signal and the second detect signal being inactive, and keeping the toggle detect signal inactive in response to an activation of either the first detect signal or the second detect signal.
