Oscillation Circuit
In the case of an oscillation circuit using piezo resonator, the
inductor in Fig.2 can be replaced by the resonator because
its impedance is inductive between fr (impedance minimum)
and fa (impedance maximum) as shown in Fig.1.
Fig.3 shows an example of oscillation circuit using 1-port
SAW RESONATOR. Rb1 and Rb2 are for DC bias. Re is a
load impedance. Cd is for power line de-coupling. CL1 and
CL2 are load capacitance to satisfy oscillation conditions.
Values of CL1 and CL2 must be evaluated to get desired
oscillating frequency.
Transistor shall be a high frequency type - fT a few GHz or
more.
SMT type transistor, resistor, capacitor are recommended
for application more than 100 MHz due to the inductance of
the lead terminals.
