Fig. Ⅲ shows the equivalent circuit of an emitter
grounding type transistor circuit. In the figure, Ri
stands for input impedance, R
impedance and ß stands for current amplification
rate.
When the oscillation circuit in Fig. 2-6 is expressed
by using the equivalent circuit in Fig. Ⅲ , it
becomes like Fig. Ⅳ . Z
the table for each Hartley type and Colpitts type
circuit.
The following 3 formulas are obtained based on
Fig. Ⅳ.

As i
oscillation, the following conditional formula can be
performed by solving the formulas of (1), (2) and (3)
on the current.
Then, as Z
the following conditional formula is obtained by
dividing the formula (4) into the real number part
and the imaginary number part.
Formula (5) represents the phase condition and
formula (6) represents the power condition.
Oscillation frequency can be obtained by applying
the elements shown in the aforementioned table to
