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
