Claim Text:
1. A voltage monitoring test circuit comprising: a switching control signal generation unit configured to receive first and second switching signals, and generate first and second switching control signals control the first and second switching, control signals such that an enable period of the first switching control signal and an enable period of the second switching control signal do not overlap with each other, where a first voltage is transmitted in response to the first switching control signal, and a second voltage is transmitted in response to the second switching control signal; and a sink pulse generation unit configured to receive the first and second switching signals and generate a sink pulse at a time when any one of the first and second switching signals is enabled, and wherein the first voltage and the second voltage having each other different constant voltage level, wherein the second switching control signal is enabled after a predetermined delay time elapses from a point of time that the first switching control signal is disabled.
