As shown in figure 3, pierce circuit is made up of capacitor charge and discharge circuit, comparison circuit and frequency dividing circuit, its principle is:
When comparator is output as low level, left side metal-oxide-semiconductor series circuit charging circuit conducting, discharge circuit cut-off are filled to electric capacity
Electricity, when capacitance voltage is higher than resistance branch voltage, comparator output high level, metal-oxide-semiconductor conducting now in parallel with a resistor and
Internal resistance is less than resistance connected in parallel, and comparator Vin- input terminal voltages are less than capacitance voltage and provide certain for discharge circuit
Time remaining, now charging circuit cut-off, discharge circuit begin to turn on, and circuit discharging makes capacitance voltage less than Vin- inputs electricity
Pressure, discharge circuit cut-off, metal-oxide-semiconductor cut-off in parallel with a resistor, charging circuit conducting enable the circuitry to persistent oscillation.In principle
In figure, as charge-discharge velocity is different, the pulse duty factor of circuit output is different, therefore is amplified using frequency dividing circuit adjustment
Device pulse duty factor and driving force is improved, spacing output circuit reduces the impact to its performance.
Circuit is using to capacitor charge and discharge, therefore the adjustment to frequency of oscillation need to only adjust its charging and discharging currents size, i.e.,
Adjust the parameters such as the breadth length ratio of metal-oxide-semiconductor, the comparison voltage of gate source voltage, capacitance size or Vin- ends and be capable of achieving frequency adjustment.Figure
Middle employing metal-oxide-semiconductor tool in parallel with a resistor plays a very important role, if not having this control circuit, oscillating circuit can find one and put down
Weighing apparatus point makes circuit keep constant output, it is impossible to realize vibration.The charging speed of circuit is understood by comparator output waveform dutycycle
Degree is less than its velocity of discharge.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this
