ADAPTIVE ANTI-AGING SENSOR BASED ON CUCKOO SEARCH ALGORITHM

摘要

An adaptive anti-aging sensor based on a cuckoo search algorithm, comprising a control module, a reference voltage-controlled oscillator, two shaping circuits, a frequency difference circuit, a resolution adjustment circuit, a 16-bit counter, a parallel-to-serial circuit, an adaptive module, and a digital-to-analog converter. A look-up table is prestored in the adaptive module; when aging monitoring is performed on a voltage-controlled oscillator in an integrated circuit, the adaptive module uses the cuckoo search algorithm to determine the optimal working voltage of the currently monitored voltage-controlled oscillator, and the control module accordingly changes the input voltage of the voltage-controlled oscillator of the integrated circuit. The present invention has the advantages that the degree of aging of the integrated circuit is reflected by monitoring the degree of aging of the voltage-controlled oscillator in the integrated circuit, and the optimal working voltage of the voltage-controlled oscillator in the integrated circuit is adaptively adjusted for adaptive aging repair of the voltage-controlled oscillator in the integrated circuit, so that the aging repair for the integrated circuit at different degrees of aging can be satisfied, the purpose of anti-aging of the integrated circuit is finally achieved, and the application range is wide.
