I am wanting to design a simple but stable sawtooth VCO with a 5 octave range, the dual power supply can be any value that is best suited, with reason. How would I begin to tackle the design process? is there steps for me to follow? would I begin by choosing the IC first? and what IC parameters are the most essential when choosing, such as slew rate, temperature ? I have already simulated a circuit in which I will base my design from but have used values from other designs. However I would like to find the relevant equations to calculate the required component values for my specific design. The plan is to design a MIDI to CV controller using a PIC, which is connect to an exponential converter to then supply a current to vary the frequency of this circuit. I understand the purpose of each component (except Rs3) but do not understand the correct way of calculating the values.
thanks in advance
