Oscillation frequency fosc. in this circuit is expressed
approximately by the following equation.
fosc.=Fr

This clearly shows that the oscillation frequency is
influenced by the loading capacitance. Further caution
should be paid in defining its value when a tight
tolerance of oscillation frequency is required.
Application to C-MOS Inverter
For the C-MOS inverting amplifier, the one-stage 4069
C-MOS group is best suited.
The C-MOS 4049 type is not used, because the three-
stage buffer type has excessive gain, which causes RC
oscillation and ringing.
Murata employs the TOSHIBA TC4069UBP as a
C-MOS standard circuit. This circuit is shown in
Fig. 4-2. The oscillation frequency of the standard
CERALOCK
circuit in Fig. 4-2.
