Abstract
The present invention discloses a voltage adjusting circuit including a first switch element, a second switch element, a third switch element, a fourth switch element, a fifth switch element, and a sixth switch element. At first, the voltage adjusting circuit performs a discharging operation on an output voltage toward a reference voltage source, and then when the output voltage level is approaching a voltage level of an input voltage source, the voltage adjusting circuit will perform the discharging operation on the output voltage toward the input voltage source instead, and thus the voltage adjusting circuit can avoid affecting the input voltage source when performing the discharging operation. In addition, the voltage adjusting circuit does not need a digital counter to perform the above dual-phase type discharging operation or multi-phase type discharging operation, and therefore cost of the voltage adjusting circuit is lower, and the voltage adjusting circuit has good accuracy.
