Abstract
A voltage detection circuit comprises a plurality of even-number voltage detection nodes, at least one odd-number voltage detection node, a voltage differential generation circuit, a selection circuit and a computing circuit. The selection circuit is for controlling the coupling relationship between the voltage differential generation circuit and the even and odd-number voltage detection nodes, so that the voltage differential generation circuit generates a voltage differential between the nodes. The computing circuit knows a voltage of a first even-number voltage detection node being as a reference voltage or obtains the voltage of the first even-number voltage detection node on the basis of the reference voltage, and respectively obtains a voltage of the nodes on the basis of the voltage differential between two adjacent nodes and the obtained voltage of a first even-number voltage detection node.
