CAPACITIVE MEASUREMENTS WITH FAST RECOVERY CURRENT RETURN

摘要

An apparatus and method for measuring the leakage current of capacitive components. A switch that grounds a terminal of a component being tested is closed while the component is charged to a desired test voltage. When this charging is complete, the switch opens so that the diode terminal is at the same potential as the input amplifier's virtual ground. An accurate and fast measurement of the leakage current of the component can be measured.
