Abstract
An active probe (1) for measuring a voltage across a high value impedance, the active probe (1) including: an impedance matching circuit (10) configured to have an input impedance at least 100 times higher than the impedance to be measured, and to deliver a low impedance signal at the output; a probe tip (6) configured to take a measurement and connected to the impedance matching circuit (10); a ground reference (G) connected to the impedance matching circuit (10); the impedance matching circuit (10) including, connected in cascade, at least one input circuit (14) and a non-inverting amplifier circuit (16) adapted to high impedance values.
