Vo；Described diode D1 is clamper Zener diode.
Refer to Fig. 1, not gate F1, electric capacity C1 and R1 constitutes low-frequency oscillation, determines frequency of oscillation, regulates resistance R1, it is possible to
The frequency of oscillation of regulation circuit, not gate F2, electric capacity C2 and resistance R4 constitute modulation circuit, determine oscillation amplitude, regulate resistance R4
The amplitude size of circuit, not gate F3 and not gate F4 can be regulated and form a buffer amplifier circuit, the oscillator signal of generation is put
Export at output end vo after great.
In sum, the oscillating circuit that this utility model gate controls, use multiple not gate to be controlled, it is possible to respectively
The amplitude of regulation vibration and frequency, circuit structure is simple, low cost, and owing to not using chip component control, anti-interference
Ability is strong.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
