Auto-Adjusted Pulse Width Circuit To ImproveMemristor Variations In ReconfigurableHigh-Pass Filter

Having many advantages, memristors have been studied for applications in many fields such as neuromorphic computing, non-volatile memory, memory and digital logic gates. Specially, memristor can be used to
design the reconfigurable filters with various cut-off frequencies. However, because of their tiny sizes, they have a lot of process variations, especially memristor thickness. These effects vary low memristance state much more than a high memristance state. To minimize these memristance variations, an auto-adjusted pulse width circuit is designed to create expected memristance for
high-pass filters regardless of various thickness variations. Therefore, the pulse width will automatically be adjusted even in case of thin or thick thickness memristor compared with nominal thickness memristor. By doing so, the high-pass fillers are reconfigurable and achieve high memristance accuracy with stable cut-off frequency in variation conditions. They also save unnecessary power loss due to shorter programming time.
