Abstract
A multi-stage voltage division circuit is provided and includes a main-stage voltage division element and a sub-stage voltage division element. The main-stage voltage division element is connected between a high-voltage end and a low-voltage end to average a high voltage and a low voltage and accordingly generates a main output voltage. The sub-stage voltage division element is connected between the high-voltage end and the low-voltage end and connected in parallel with the main-stage voltage division element. The sub-stage voltage division element averages the main output voltage and the low voltage to generate a lower output voltage. The sub-stage voltage division element averages the high voltage and the main output voltage to generate an upper output voltage. Therefore, in the situation of generating the same amount of divided voltages, the multi-stage voltage division circuit has higher driving efficiency and generates stable divided voltages to loads.
