Embodiment Construction
[0021] The present invention aims to propose a new type of memristor-based analog-to-digital converter with high precision, low power consumption, and small chip area. Memristor (MEMRISTOR) is the fourth type of Basic passive components. The resistance value of the memristor can be programmed at the maximum resistance R MAX and minimum resistance R MIN any resistance value between; in the present invention, voltage pulses are used to program the resistance value of the memristor, and the resistance value of the memristor will gradually change with the number of pulses; in order to realize the gradual decline of the resistance value of the memristor, the present invention adopts A positive voltage pulse is applied to the top electrode of the memristor to program the resistance value of the memristor, so that the resistance value of the memristor can gradually decrease in a step-like manner by controlling the pulse amplitude, frequency, duty cycle and number of pulses.
