Abstract
A direct current (DC) power rail probe includes a single-ended probe tip, and a two-path circuit having an input coupled to the single-ended probe tip and an output configured for connection to measurement equipment such as an oscilloscope. The two-path circuit includes an alternating current (AC) path in parallel with a feed-forward (FF) path, the AC path including a capacitive element, and the FF path including a series connection of at least one resistive element and an amplifier. The probe tip and two-path circuit are selectively operable in a non-attenuating mode and an attenuating mode.
