Abstract
Circuitry for testing an integrated capacitor that includes a first capacitor, a supply node for connecting to a voltage supply, a test node for connecting to the integrated capacitor, and a charge monitoring circuit. The circuitry is operable in a sequence of states including a first state in which the first capacitor is connected to the supply node and is disconnected from the test node so as to charge the first capacitor to a test voltage and a second state in which the first capacitor is disconnected from the supply node and is connected to the test node to apply the test voltage to the integrated capacitor. The charge monitoring circuit is configured to monitor a charge transfer from the first capacitor to the integrated capacitor in said second state and to generate a measurement value based on an amount of the charge transfer.
