Abstract: The present disclosure relates to a detection circuit for detecting oscillations of a regulated supply signal. The detection circuit includes a filter circuit to filter the regulated supply signal in order to obtain a filtered supply signal. A peak value detector circuit is designed to detect an extremum of the filtered supply signal. A comparator circuit is designed to compare the detected extreme value with a threshold value and to indicate an understepping or exceedance of the threshold value.

Abstract: A radar monolithic microwave integrated circuit (MMIC) includes a trigger encoder configured to receive a clock signal comprising a plurality of clock pulses having a fixed amplitude and a trigger signal configured to indicate trigger events. The trigger encoder is configured to encode the trigger signal into the clock signal to generate a distributed clock signal by skipping at least one clock pulse of the plurality of clock pulses to indicate a trigger event. The radar MMIC is configured to output the distributed clock signal having the at least one clock pulse skipped to indicate the trigger event. The radar MMIC is configured to receive the distributed clock signal as a received distributed clock signal. The radar MMIC further includes a radar operation controller configured to detect the trigger event based on the received distributed clock signal and initiate a radar operation based on detecting the trigger event.
