Abstract
The present disclosure provides an oscillating circuit and an electronic device; the oscillating circuit includes a capacitor charging and discharging circuit unit, a voltage comparison circuit unit and a threshold voltage generation circuit unit; the oscillating circuit uses the capacitor charging and discharging and the hysteresis effect of the capacitor charging and discharging circuit unit to achieve oscillation based on the negative feedback regulation constituted by the voltage comparison circuit unit and the threshold voltage generation circuit unit, which is different from the traditional oscillating circuit based on capacitance and inductance; the oscillating circuit does not adopts inductors, has relatively low power consumption, and outputs oscillation signals with frequencies that vary with currents, and when the oscillating circuit is used to provide clock signals for the sensor, it can be integrated with a sensor signal processing circuit to realize the miniaturization and integration of the sensor system.
