Fig.12 Power dissipation of source follower as a
function of RSF; VCOIN at 1⁄2 VDD; R1 = ∞ ;
R2 = ∞ .
For VCO linearity:
f′o
=
-f-1----+-----f--2-
2
lin. = f--′--o--f--′–-o---f--o- × 100%
Figure 13 and the above
formula also apply to
source follower linearity:
substitute VSF OUT for f.
∆V = 0,3 V at VDD = 5 V
∆V = 2,5 V at VDD = 10 V
∆V = 5 V at VDD = 15 V
