Abstract
A method provides that, when a driver circuit is deactivated, a first capacitor disposed at an output of the driver circuit is placed at a first potential. The driver circuit is then activated at a first point in time, so that a current flows between its output and the first capacitor. The flow of current between the output of the driver circuit and the first capacitor is interrupted at a second point in time and the potential at the first capacitor is subsequently determined as a measure of the drive capability of the driver circuit.
Claims5
A method for determining a drive capability of a driver circuit of an integrated circuit, which comprises:
- deactivating the driver circuit and placing a capacitor disposed at an output of the driver circuit at a first potential;
- activating the driver circuit at a first point in time so that current flows between the output and the capacitor;
- interrupting the current flowing between the output of the driver circuit and the capacitor at a second point in time;
- and
- determining subsequently a potential at the capacitor as a measure of the drive capability of the driver circuit.
