Abstract
The voltage controlled oscillator (VCO) is the oscillator circuit whose output frequency is controlled by a variable dc control voltage. The VCO can be used in many applications such as neural stimulation and heart stimulation. Neural stimulation is one of the most important stimulations in biomedical engineering because it is used to treat the chronic pain such as Parkinson’s disease.
In this thesis, the voltage controlled oscillator circuit is represented in two different designs. The first design uses resistors and the other one uses memristors and both shapes are practically applied. The first one is a voltage controlled oscillator circuit by resistors which uses the fixed resistor and it is designed to work in the low frequency range but the design needs large silicon area to be fabricated which makes its manufacturing cost is high. The second one is a new proposed voltage controlled oscillator using memristors which can be used in low frequency application such as neural stimulation and requires less area and thus less cost. Finally, the thesis provides a comparison between VCO based resistors and memristors for different applications. The comparison helps to recognize the advantages and disadvantages of each type regarding their applications.
