Abstract: A power supply noise measurement device for inclusion with an integrated circuit, the integrated circuit having a functional block, the noise measurement device comprising: a signal generator configured to provide a clock signal to the functional block, an antenna comprising a transistor, and being located proximate to the functional block, the antenna being configured to receive the clock signal from the signal generator, and a jitter estimator configured to provide a measure of the relative jitter between a signal output from the antenna and a reference clock signal, wherein the transistor of the antenna receives electrical power from the same power source that delivers power to the functional block.
