A voltage droop detection circuit can be used to detect a voltage droop in an integrated circuit (IC) device. The voltage droop detection circuit may include a chain of inverting stages, and each inverting stage may include a P-type transistor and an N-type transistor. The chain of inverting stages can be initialized to alternating logic states during an initialization phase of a clock cycle, and an evaluation pulse can be inputted into the chain of inverting stages during an evaluation phase of the clock cycle. A voltage droop may be detected if a number of inverting stages that are able to switch output logic states from their respective initialized logic states is smaller than a nominal value indicating a number of inverting stages that are able to switch their respective output logic states under normal voltage condition.
