Compensation of degradation of performance of semiconductor devices by clock duty cycle adaptation

摘要

The device degradation of integrated circuits may be compensated for by appropriately adapting the duty cycle of the clock signal. For this purpose, a correlation between the duty cycle and the overall performance characteristics of the integrated circuit may be established and may be used during the normal field operation of the device in order to modify the duty cycle. Hence, an efficient control strategy may be implemented since the duty cycle may be efficiently controlled, while at the same time a change of clock signal frequency and/or an increase of supply voltage may not be required.
