This paper discusses voltage-controlled M-M relaxation oscillator with analytical and circuit simulations. The introduced circuit has two different configurations based on the polarities of memristor; whether they are in the same direction or in the opposite direction. The Analytical formulas are function of the reference voltage such as the oscillation frequency and oscillation conditions for each case are derived with some numerical examples. The circuit simulations are introduced to validate the mathematical concepts as well as the effect of the reference voltage which can be used in frequency modulation application. A comparison between the two oscillators is presented versus different parameters. Finally, similar discussion based on asymmetric voltage controlled oscillator is introduced where different frequency ranges can be obtained. © 2016 IEEE.
