Abstract:
1. A circuit configured for checking a degree of a matching between a first energy-storage element and a second energy-storage element, wherein a second terminal of the first energy-storage element is coupled to a first terminal of the second energy-storage element, and the first energy-storage element and the second energy-storage element are electrically coupled in series; the circuit comprising: a linear resistor, wherein a first terminal thereof is electrically coupled to a signal output terminal of the circuit and a second terminal thereof is electrically coupled to a second terminal of the first energy-storage element and a first terminal of the second energy-storage element; and a power supply having an output terminal electrically coupled to the second terminal of the linear resistor, applying a plurality of voltages to a first terminal of the first energy-storage element and a second terminal of the second energy-storage element to ground, whereby the degree of the matching between the first energy-storage element and the second energy-storage element is obtained.
