Abstract
By powering an electronic component operating in an ultra-low power mode from a pre-charged measuring capacitor and measuring the time to discharge the capacitor to a trip voltage level, measurement data can be obtained. In some implementations, the capacitance of the capacitor can be obtained by adding a known current to the unknown current drawn from the capacitor and calculating the capacitance using a mathematical formula.
