I have this VCO circuit taken from the net. I build the circuit in LTspice and It works perfectly fine but I want to change the frequency of the signal output. Basically what I wanted to do is to have a signal that is going above and below a center frequency by 4khz with a sensitivity of 1khz/v.
For example, Fc = 132khz, Fmin = 128khz, Fmax = 136khz. I just want to know what components should I change in my circuit. A formula would be helpful If anyone here is familiar with the circuit. Thank You!
