The above oscillators are arranged as Colpitts os-
cillators and the structure is redrawn here to em-
phasize the split capacitance used in a Colpitts
oscillator It should be noted that this oscillator
configuration is just one of literally hundreds
possible and the configuration shown here does
not necessarily represent the best solution for all
applications Crystal manufacturers are very in-
formative sources on the design and use of oscil-
lators in a wide variety of applications and the
reader is encouraged to become familiar with
them
Colpitts Oscillator
4584 – 12
C1 is to adjust the center frequency C2 DC iso-
lates the control from the oscillator and V1 is the
primary control device C2 should be much larger
than CV so that V1 has maximum modulation
capability The frequency of oscillation is given

4 KVCO represents how much the VCO frequen-
cy changes for each volt applied at the control
pin It is assumed (but probably isn’t) linear
about the lock point (25V) Its value depends
on the VCO configuration and the varactor
