Abstract
Methods and devices to measure threshold voltages of electro-mechanical systems devices are disclosed. The threshold voltages are determined based on which of multiple test voltages cause the devices to change states. State changes of the device are detected by monitoring integrated current or charge used to drive the test voltages.
