Memristor based Relaxation Oscillator for Biomedical applications
It is well known and must be appreciated that various organs in the human body such as the nervous system and heart work at very low frequency. Therefore it becomes necessary that whenever these organs have to be treated to cure certain diseases, the machinery used should also work at the same minute frequency. This crucial requirement is achieved by using low-frequency oscillators to provide clock pulses in the circuitry of the machines. One such widely used oscillator is relaxation oscillator. Though this oscillator provides low frequencies up to the certain range, the circuit size and power consumption have to be compromised for the lower frequencies. In this paper, we consider a typical relaxation oscillator generating a frequency of 454.54Hz. We go on replacing the resistors in all possible combinations (around 7) to generate a frequency in the band of 250Hz to 750Hz. we design, simulate and prove that memristor-based relaxation oscillators [MERO] provide lower frequencies with lower delay along with compact circuit size and low power consumption.
