Abstract
An adaptive anti-aging sensor based on a cuckoo 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 lookup 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 algorithm to determines 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.
