To obtain optimum temperature stability, C1 must be as small as possible but larger than 100 pF.

In (b), the frequency stability for R1 = R2 = 10 k at 5 V is also given (curve A). This curve is set by the total VCO bias current, and is
not simply the addition of the two 10 k stability curves. C1 = 100 pF; V
