(generally, lead zirconium titanate: pzt.) the oscillation mode varies with resonant frequency. the table on the right shows this relationship. as a resonator device, quartz crystal is well-known. rc oscillation circuits and lc oscillation circuits are also used to produce electrical resonance. the following are the characteristics of ceralock ? . ? high stability of oscillation frequency: oscillation frequency stability is between that of the quartz crystal and lc or rc oscillation circuits. the temperature coefficient of quartz crystal is 10 ?6 /c maximum and approximately 10 ?3 to 10 ?4 /c for lc or rc oscillation circuits. for comparison these, it is 10 ?5 /c at ?20 to +80c for ceramic resonators. ? small configuration and light weight: the ceramic resonator is half the size of popular quartz crystals. ? low price, non-adjustment: ceralock ? is mass produced, resulting in low cost and high stability. unlike rc or lc circuits, ceramic resonators use mechanical resonance. this means it is not basically affected by external circuits or by the fluctuation of the supply voltage. highly stable oscillation circuits can therefore be made without the need of adjustment. the table briefly describes the characteristics of various oscillator elements. 1 vibration mode and frequency range frequency (hz) vibration mode 1 flexural mode 2 length mode 3 area expansion mode 4 radius vibration 5 shear thickness mode 6 thickness expansion mode 7 surface acoustic wave 1k 10k 100k 1m 10m 100m 1g characteristics of various oscillator elements name symbol price size adjust- ment oscillation frequency initial tolerance long-term stability lc lower cost big required 2.0% fair [note] : ? show the direction of vibration cr lower cost small required 2.0% fair quartz crystal expen- sive big not required 0.001% excellent ceramic resonator inexpen- sive small not required 0.5% excellent p17e.pdf 2012.10.31

(refer to note 2 on page 8) considering the limited frequency range of fr ? f ? fa, the impedance is given as z=re+j le (le ? 0) as shown in fig. 2-4, and ceralock ? should work as an inductance le (h) having the loss re ( ). 2 principles of ceralock ? fr=1/2 l 1 c 1 fa=1/2 l 1 c 1 c 0 /(c 1 +c 0 )=fr 1+c 1 /c 0 (2-1) (2-2) (2-3) qm=1/2 frc 1 r 1 (qm : mechanical q) symbol fig. 2-4 equivalent circuit of ceralock ? in the frequency band fr ? f ? fa re le r 1 : equivalent resistance l 1 : equivalent inductance c 1 : equivalent capacitance c 0 : parallel equivalent capacitance re : effective resistance le : effective inductance fig. 2-3 electrical equivalent circuit of ceralock ? l 1 c 1 c 0 r 1 fig. 2-2 impedance and phase characteristics of ceralock ? 10 4 10 3 10 2 10 90 0 -90 10 5 frequency (khz) fr fa 2 p17e.pdf 2012.10.31

(note 1) the relationship between the size of the resonator and the resonant frequency is described as follows. for example, the frequency doubles if the thickness doubles, when thickness vibration is used. the following relationship is obtained when the length of the resonators is y , the resonance frequency is fr, the speed of sound waves travelling through piezoelectric ceramics, and the wavelength is . fr . y = const. (frequency constant, fr . t for the thickness) = 2 y c = fr . = 2fr . y as seen in the above formula, the frequency constant determines the size of the resonator.

(refer to note 3 on page 11.) in an lc network, the inductor is replaced by a ceramic resonator, taking advantage of the fact that the resonator becomes inductive between resonant and anti- resonant frequencies. this is most commonly used in the colpitts circuit. the operating principle of these oscillation circuits can be seen in fig. 2-7. oscillation occurs when the following conditions are satisfied. loop gain g = ~ ? 1 phase amount (2-6) = 1 + 2 = 360 n (n = 1, 2, ? ) in colpitts circuit, an inverter of 1 = 180 is used, and it is inverted more than 2 = 180 with l and c in the feedback circuit. the operation with a ceramic resonator can be considered the same. c l1 c l2 l l 1 l 2 c fosc. = (hartley circuit) 1 fosc. = (colpitts circuit) 1 c l1 c l2 c l1 + c l2 (2-4) (2-5) fig. 2-6 basic configuration of lc oscillation circuit amplifier 1 feedback circuit feedback ratio : phase shift : 2 fig. 2-7 principle of oscillation colpitts circuit hartley circuit oscillation conditions loop gain g= ? 1 phase shift = 1 + 2 =360 n p17e.pdf 2012.10.31
