Abstract
A monitor circuit for monitoring a clock signal is described. In accordance with one example of the disclosure, the monitor circuit includes a pulse generator and a comparator circuit. The pulse generator is configured to generate a sequence of pulses synchronous to the clock signal, wherein each pulse has an edge with a monotonously rising or falling signal level. The comparator circuit receives the sequence of pulses and is configured to detect, for each clock cycle of the clock signal, whether or not the signal level of the sequence of pulses is outside a desired range at a specific time instant within the clock cycle of the clock signal.
