Abstract
A self-checking circuit includes: an edge detector configured to output an edge detection signal having a pulse generated during detection of an edge of a pulse signal having a pulse train; a charging and discharging circuit configured to perform a charging operation and a discharging operation based on the edge detection signal to generate a detection voltage; and a comparison circuit configured to check whether the pulse signal is normal, based on the detection voltage, to output a checking signal.
