ABSTRACT:
Capacitance measurement apparatus in which an output signal representative of the capacitance of a capacitor under test is provided without requirement for absolute measurement of the voltage level or absolute measurement of time interval. A first signal is provided representing the voltage difference between the charge levels of the capacitor. A second signal is provided representing the average current from the capacitor during the time interval that the capacitor undergoes a change in its charge states. The ratio of the second signal to the first signal is representative of capacitance.
