Hi,
I'm having some trouble adding voltage control to an oscillator cct? For a group project we have been tasked with creating a sine wave output that's frequency must be adjusted between 1kHz to 100kHz with a 0 to 5 Volt input. Some circuits we have looked at are the Wein Bridge, Colpitts, Clap, and RC phase shift. Some searches have come up saying to implement varactor diodes in the Clapp or Colpitts circuits. However, I have been finding it easier to tune the frequency of the output with the RC phase shift network, but don't know how to implement voltage control to it. Any help would be greatly appreciated.
Cheers.
