Abstract

A new method to detect the power supply and ground noise (PSN) in ICs is proposed in this paper. We improve the conventional peak detector sample and hold circuits (PDSH) and apply them to detect the PSN. The maximum overshoot or undershoot noise will be both detected and held in a holding capacitor. This consequence enables the next processing circuit to operate conveniently without further speed restriction. The noise detector is verified able to detect 1 GHz PSN with the magnitude from 10% to 45% VDD within 5% error. As compared to the prior art, both the detection range and speed are improved significantly.
