AVX/Kyocera produces a broad range of high quality
ceramic resonators covering both the kilohertz and
megahertz frequency ranges. The high quality and extensive
coverage of this product line allows optimum design of
almost any oscillating circuit.
Ceramic resonators stand between quartz crystal
oscillators and LC/RC oscillators in regard to accuracy but
are considerably smaller, require no adjustments, have
improved start-up times, and are low in cost.
Their oscillation is dependent upon mechanical
resonance associated with their piezoelectric crystalline
structure. These materials (usually barium titanate or lead-
zirconium titanate, PZT) have large dipole movement which
causes the distortion or growth of the crystal by an applied
electric field. The resonance frequency depends on the
vibration mode as shown in Figure 1.
A basic feedback circuit is shown in Figure 2. It consists
of an amplifier with a 180° phase shift and attenuator. A
negative polar output (volt) is obtained with an amplitude
equal to the gain of the amplifier times the input voltage (G
×
V
IN
). After the signal goes through the feedback network
with an attenuation ratio of , a negative polar wave equal
to
×
(G
×

IN
) is fed back to the input. If this feedback is
greater than the initial input voltage (V
IN
), oscillation will
occur. This satisfies the two conditions necessary for
oscillation:
