[sdiy] VCO Integrator cap/resistor selection

[Justin Owen]

Hello,

As a general rule, in the integrator of a VCO, is there any advantage to going for the smallest capacitor possible (and bigger input resistors) to get the frequency range you're after?

I've noticed that my 10nF cap - while working fine - is looking kind of fat in comparison to just about every other design I've seen.

Just curious.

Oh - thanks again to those who helped out with the DC summing questions. Much appreciated.

Cheers,

Justin
