CURRENT MEASURING DEVICE, TESTING DEVICE, CURRENT MEASURING METHOD AND TESTING METHOD

摘要

A current measuring device measures a current which an electronic device receives from an input terminal. The current measuring device is provided with a first capacitor which accumulates a reference supply voltage to be a reference of a voltage to be supplied to the electronic device while the current is being measured; a first switch which connects a power supply to the first capacitor before measuring the current, permits the first capacitor to accumulate the reference supply voltage, and cuts the power supply from the first capacitor while the current is being measured; a current supplying section which supplies the electronic device with the current based on the reference supply voltage accumulated in the first capacitor and a terminal voltage of the input terminal; and a first current measuring section which measures a supply current supplied to the electronic device.
