Oscillation Circuit
s Theory of Oscillation Circuit
Oscillation circuits using LC or quartz crystal are called
'Feedback Oscillators'. Feedback oscillator consists of an
amplifier and a feedback circuit.
The circuit oscillates, with no input signal applied from
outside of the oscillator, when feedback signal from the
output of the amplifier has the same amplitude and phase to
the input signal. The conditions required to the feedback to
enable oscillation are as follows;
Amplitude : G =
α + β U 0 [dB]
Phase :
θ = θ1 + θ2 = 360 x n [degree]
(n: Natural number)
Colpitts is one of the popular oscillation circuits. Basic
structure of Colpitts oscillator is as shown in Fig.2. The
oscillating frequency is approximately same to resonant
frequency of L, CL1 and CL2.
fosc = 1 / (2
π ( L x CL1 x CL2 / ( CL1 + CL2 ))1/2)
1-port SAW RESONATOR is a kind of two terminal resonant
device utilizing piezoelectricity, like quartz crystal bulk wave
resonator or ceramic resonator. The equivalent circuit of
1-port SAW RESONATOR is same to that of quartz or
ceramic resonator, and therefore, impedance characteristics
of SAW RESONATOR is as shown in Fig.1.
