Memristor Based Oscillator

In this paper memristor based RC phase shift oscillator and Colpitts oscillator have been proposed. In the proposed oscillators resistors and inductors present in the conventional circuits have been replaced by memristors. Memristor characteristics like nano scale dimension, low power consumption and electronic programmability help in achieving high performance oscillators. LTspice has been used to simulate the conventional and proposed circuits. These simulaton results show that RC phase shift and Colpitts oscillators can be tuned in the frequency range of 3 to5 kHz and 52 to 58 kHz respectively, if controlling voltage is changed from 0.3 to 1.8 V.
