Voltage Control Oscillator

I. Introduction
Report Outline

1. Purpose of the Project

This project is to design voltage control oscillator.  In this
report, I will show how to calculate the resistance and the capacitor
to get any limit value for the frequency at the output.

2. Gains ( Voltage, Current
& Power )

The voltage gain for the circuit I used to produce the frequency is
equal to Av = 0.52 measuring Av = 0.5333 Pspice and the current gain
is equal to Ai = -0.39 measuring   Ai = -0.45 Pspice. 
So the power gain is equal to Ap = 0.2028 measuring Ap = 0.2399 Pspice. 
To get understand who I get these result go through my report to show
you how I built my circuit.

3. What is Oscillator

An electronic oscillator may define in any one of the following four
ways:

A circuit
