WebThe glitch-clock pulse by abnormal clock generation causes the inversion of flip-flops status. In this paper, we propose an on-chip clock controller architecture to detect automatically clock failure and to switch the safe backup clock. The implemented edge detector (ED) unit identifies the abnormal low-frequency status of the clock source.
