Abstract
The present invention provides a digital sensor including a first delay circuit, a second delay circuit and a sampling circuit. The first delay circuit is configured to delay a clock signal to generate a first clock signal. The second delay circuit is configured to delay the clock signal to generate a second clock signal. The sampling circuit is configured to sample the first clock signal according to the second clock signal to generate a first fault detection result.
