Abstract
Provided is a system for testing a reference voltage circuit applicable to a reference voltage circuit. The reference voltage circuit includes a bandgap reference voltage circuit, switching elements, a first capacitor, a second capacitor and a comparator. The testing system includes a control logic unit. In a test mode, the control logic unit adjusts an allowable value of the comparator to speed up the suitability test of the switching elements.
