In-Situ Measurement of Supply-Noise Maps with Millivolt Accuracy and Nanosecond-Order Time Resolution

Abstract
An in-situ measurement scheme for supply-noise maps under running applications in product-level LSIs was developed. This scheme was used to successfully measure 69-mV local supply noise with 5-ns time resolution in a 3G cellular phone processor. It will thus help in designing power-supply networks and visibly verifying the quality of a power supply
