It is common and simple to utilize an inverter for the
Colpitts circuit with CERALOCK
Fig. 2-8 shows the basic oscillation circuit with inverter.
In an open loop circuit by cutting at point Ⓐ , it is
possible to measure loop gain G and phase shift θ .
Fig. 2-9 shows the actual measuring circuit, and an
example of the measuring result is shown in Fig. 2-10.
